Name five terms used for contemporary society
Information age, computer age, post-industrial society, network society, fourth industrial revolution.
Why “multiple digital societies”?
Access, use and skills are unevenly distributed, so people under the same infrastructure live very different digital lives.
What does “post-industrial society” emphasise?
That services and knowledge work have replaced manufacturing as the main form of employment.
A named example of exclusion from digital society
The ITU estimated in 2023 that around 2.6 billion people had never used the internet.
The three digital divides
Access (can you connect at all), use (how, how often, how well), and skills and outcomes (what you can achieve online).
How many people have never used the internet?
Around 2.6 billion, on the ITU's 2023 estimate — roughly a third of the world.
Impact vs implication of the divide
Impact: some people cannot get online. Implication: services designed for the majority make the excluded minority poorer and less visible.
A within-country divide
Rural against urban coverage, income and shared devices, age, disability, language, and in several regions gender.
Six milestones in digital society
Integrated circuit (1958), microprocessor (1971), personal computer (1981), the internet (ARPANET 1969), online social networks (2000s), mobile and cloud (2007 onwards).
Internet vs World Wide Web
The internet is the network of networks. The web is ONE service on it — linked documents fetched by a browser. Proposed 1989, public 1991.
Why did the microprocessor matter?
A whole processor on one chip, so computing could be embedded in other products instead of occupying a room.
The pattern across all milestones
Smaller and cheaper, and more connected. Almost everything else in the course follows from those two forces.
Define: bit
A single binary digit — 0 or 1. The smallest unit of data.
Define: byte
Eight bits, giving 256 possible values.
Why binary rather than ten states?
A circuit can tell on from off reliably even as voltage drifts; ten levels would make errors far likelier.
Four things binary representation makes possible
Exact copies, compression, encryption, and storing text, sound and images in one system.
Analogue vs digital
Analogue is continuous and may take any value in its range; digital is discrete and takes one of a finite set of values.
What is sampling?
Measuring a continuous signal at intervals and recording each measurement as a number, so it can be stored digitally.
The two sampling choices
Sample rate (how often you measure) and bit depth (how finely each measurement is recorded).
Is digital better than analogue?
It is more robust — copies do not degrade. It is not automatically more faithful: a digital recording is always an approximation.
Define: digitization
The conversion of analogue data or information into a digital form.
Four threats to digital preservation
Media decay, format obsolescence, hardware obsolescence, and link rot.
Why is digitizing an ongoing cost?
Formats and media keep dying, so the material must be migrated indefinitely or the copy becomes unreadable.
Why is digitization not neutral?
What gets scanned first is what later gets found, cited and taught; the unscanned quietly becomes invisible.
Define: digitalization
The use of digital systems to change the structure or operation of an organization.
Digitization vs digitalization
Digitization converts the MATERIAL and leaves the process alone. Digitalization changes the ORGANIZATION — roles, structure, model.
Four motives for digitalizing
Cost, speed, reach, and the data every digitalized process produces.
Four underestimated costs
Exclusion of users, fragility when one outage stops everything, deskilling of staff, and surveillance of workers.
Define: change (digital society)
The evolution, transformation, adaptation or movement from one form, state or value to another.
Which fields study change?
History, science and technology studies (STS), and future studies.
Evolution vs transformation
Evolution is small steps — a change of degree. Transformation is a change of kind: the thing becomes something else.
What is a technological revolution?
A change deep enough that the arrangements built around the old way stop working.
The four questions for evaluating a change
Who gains and loses? Who was asked? When are you asking? Compared with what?
Why do two accurate accounts disagree?
The gains and the costs fall on different people, so both can be accurate and reach opposite conclusions.
The sharpest comparison
Not against the past, but against what could have been built instead.
Why do costs surface late?
Benefits are immediate and measurable; costs fall slowly on fewer people and are harder to count.
The three positions on technological change
Technological determinism, social shaping, and co-production.
Define: technological determinism
The view that a technology arrives and society rearranges around it — as though nobody designed, funded or deployed it.
The evidence against determinism
The same technology produces very different outcomes in different societies — Estonia's internet voting against internet shutdowns.
What does “examine” ask for?
Uncovering the assumptions and interrelationships behind a claim, not only agreeing or disagreeing.
Continuity vs discontinuity
Continuity: a new method for a need that already existed, which old arrangements can adapt to. Discontinuity: a break that needs new rules.
The clearest test for a real break
Has a judgement that used to be made by a person moved into a system?
Why write about continuity?
It is the half most answers omit, and it is usually where the surprising point is.
The judgement to reuse on automated decisions
Continuous in purpose; discontinuous in scale and reviewability — and it is the second pair that makes it a new problem.
Define: expression (digital society)
The act, process or instance of representing an idea, feeling or identity in a form others can receive — words, images, sound, video, design or code.
What step did digital systems add?
A platform that decides how far an expression travels, between expressing it and being heard.
The line to learn
Publishing became free; reach did not. Reach is granted by a system.
What is context collapse?
Online, every audience receives the same message at once, so something written for one group lands badly with another.
Functions of expression
Storytelling, persuasion, protest, art, and showing identity.
Why is targeting an accountability problem?
Only the targeted person sees the message, so there is no shared record for a journalist, rival or regulator to challenge.
What got harder for protest?
Organising unseen — the same tools that make it fast also record who took part.
The judgement on platforms and political expression
Access to speak improved dramatically; the conditions for a shared, checkable public argument got worse. Both are real.
What does expression do to communities?
It brings people together AND divides them, using the same property: people finding others who share something.
Who gains most from online community?
People who are rare where they live — a rare condition, a scattered diaspora, an identity not accepted locally.
What does engagement ranking amplify?
Agreement within groups and conflict between groups, because both hold attention.
The judgement to reuse
Platforms unite and divide by the same mechanism, so the balance depends on what the ranking rewards.
Define: identity (digital society)
What defines a person, group, social entity or organization and distinguishes it from others.
The three layers of online identity
Declared (you wrote it), recorded (observed as you use the service), inferred (estimated from the recorded).
Which layer matters most?
The inferred one. It decides what you are shown, offered and charged — and you cannot see or correct it.
Why does verification carry power?
Whoever verifies identity decides who can act. A failed fingerprint check under Aadhaar can block food someone is entitled to.
Why is identity not static?
It changes over time and according to context — a person at 14 and at 24, or at work and among friends.
Define: context collapse
Online, every audience receives the same message at once, so one presentation has to serve all of them.
Why can an old record not be corrected as false?
It was accurate at the time. The problem is relevance rather than truth — which is the ground the right to be forgotten stands on.
What does de-listing do?
Removes a search result under a person's name. The original page stays published.
Define: intersectional identity
A person holds several characteristics at once and they overlap — the combination is its own position, not the sum of its parts.
The characteristics the guide names
Age, nationality, religion, culture, gender, sexuality, race, ethnicity, and social and economic class.
Why does separate fairness testing fail?
Each test averages over everyone with that characteristic, so a small group at the intersection disappears into the average.
Why is a model worst at intersections?
The fewest training examples exist for those combinations — and that is knowable before training begins.
Define: power (digital society)
The ability to influence or control people, events or resources.
Four ways power is exercised online
Setting defaults, controlling access, deciding visibility, holding information.
Why are defaults the strongest lever?
They need no enforcement and give nobody anything to object to, yet almost nobody changes them.
Why is visibility pressure hard to challenge?
A ranking drop removes a seller's customers without removing the seller — so the platform can truthfully say it banned nobody.
Define: structural power
Power produced by how a system is arranged, which continues without anybody deciding to use it.
Three structural sources of power
Network effects, switching costs, infrastructure position.
Why do conduct remedies fail against structure?
The position produces the outcome whoever occupies it — a kinder owner of the same position holds the same power.
Portability vs interoperability
Portability attacks switching costs; interoperability attacks network effects. Only together do they let you leave without losing people.
The three-question power test
Who decides? Who gains? Who bears the cost of an error?
Why is the error question strongest?
In almost every system the decision and the gain sit in one place and the cost of error sits with somebody else.
Why does an error weigh differently?
For the organisation it is an acceptable percentage; for the person it is their whole outcome.
What changes the distribution of risk?
A real route to human review — which makes it a design question rather than a verdict on automation.
Define: digital space
An environment created by digital systems where people meet and act, whose boundary and rules are set by its owner.
The three decisions that construct a space
Who may enter, what may be said, what is shown first.
What is unique to digital space?
Two people in the same space are shown different things, so there is no shared view to point at.
Digital space changing physical space
Short-term rentals made a flat worth more to visitors than to residents, so housing left the rental market in Barcelona.
Four functions of a space
Gathering, working, trading, learning.
What is function collapse?
Four functions share one online space, so one rule set has to serve all of them and nobody knows which function others are in.
What fails to move online?
The part nobody had written down, because the room used to do it — noticing a lost student, the unplanned conversation.
Why are privacy settings walls?
Channels, close-friends lists and second accounts are people rebuilding by hand the separations a single space removed.
The four access choke points
A device and the skill, a connection, an unblocked route, being shown.
Which barrier is largest and quietest?
Not having a device or the skill — it affects most people and looks like nobody's decision.
Why does work flow differently?
The task crosses the border instead of the worker, so labour rules stay where the worker is.
Why are shutdowns hard to judge?
They stop the reporting of what happens during them, removing the evidence anyone would need to hold the decision to account.
The four scales
Personal, local, national, global.
The three dimensions
Scale — how many. Time — how long. Reach — how far.
The usual scale mismatch
Decided at company scale, harm lands at personal scale, and only national scale can act.
What decides a country's regulatory reach?
Market size, not sovereignty — so formally equal countries have very unequal power over the same platform.
Define: system
A set of connected parts where what one does changes what the others do, so the whole behaves in ways no part does alone.
Why do fixes get absorbed?
The other parts respond, changing their own behaviour until the system returns to where it started.
Which change holds?
A change to the connections — what is measured, rewarded or paid for — rather than to quantity.
The sentence to add to any recommendation
“What will push back is…” — naming the response is what turns a wish into an answer.
The five words for describing a system
Elements, connections, boundary, purpose, feedback.
Why does the boundary matter?
Everything outside it is treated as fixed, so it decides which solutions the analysis can even consider.
How do you find a system's purpose?
Read it from what the system reliably produces, not from what its owner says it is for.
Define: feedback
Output returning as input, so the system learns from behaviour it caused — which is why systems drift.
The three shapes of change
Steady (returns to a level), growing (each round bigger), tipping (flips and stays).
Why is growing noticed late?
No single step is unusual, so nothing triggers attention until the total is already large.
Why is tipping dangerous?
Removing the pressure does not undo the change — the way back is not the way you came.
What does each shape need?
Steady: change the rule. Growing: act early. Tipping: keep a margin.
Define: model
A simplified version of something, built to answer one question — useful because of what it leaves out.
The test to apply to any model
What did it leave out, and does that matter for the question being asked of it?
Model, simulation, visualization
A model simplifies; a simulation runs a model forward in time; a visualization shows data so a person can read it.
Why are charts persuasive?
They are read in about a second, and axis, scale and colour have already made an argument by then.
Define: value
Something a person or group holds to be important — privacy, safety, fairness, freedom.
Define: ethics
The reasoning about what to do when two values require opposite actions.
Why is listing values weak?
Everyone is in favour of all of them, so the list contains none of the disagreement.
What makes a position ethical?
Its reasons are stated, so somebody who disagrees can examine and answer them.
The four guides to action
Personal values, group norms, written codes, law.
Why are written codes weak?
Written by the organisation and enforced by nobody — and afterwards they can be shown as evidence of care.
Why is law structurally late?
A legislature cannot write a rule about something nobody has seen yet, so the other three carry the years in between.
The modern compromise
A legal duty to achieve an outcome, with the industry deciding the method — roughly the EU AI Act's approach.
The four rungs a value climbs
Personal preference, community expectation, national rule, global agreement.
Where does enforcement stop?
At the national rung — nothing above the state carries a penalty of its own.
Why do voluntary global agreements underperform?
They bind only the countries already willing, because declining costs nothing.
Why do societies protect privacy differently?
They aim the same value at different threats — commercial collection in one place, state access in another.
The four ethical frameworks
Consequences, duties, rights, character.
The question each one asks
More good than harm? Is the act itself wrong? Does it take something that may not be taken? What does it make normal?
Why do consequences verdicts shift?
They depend on the numbers, so new evidence can reverse the verdict.
How to use frameworks in an answer
Run two on the case, show they disagree, then say which you follow here and why.
Three places values enter a design
Who is in the room, what the default is, what gets measured.
Why does unmeasured harm persist?
Nothing reports it, so it cannot influence anything the team does next — measurement decides what improves.
Answering “technology is neutral”
Neutral about purposes, not neutral about outcomes: it does not care what you want, but it makes some results far easier.
Values built in on purpose
Privacy by default, accessibility requirements and the right to repair are values deliberately designed in.
The four steps of DIKW
Data (raw facts), information (data with context), knowledge (a pattern you can act on), wisdom (knowing whether you should).
Define: data
Raw facts, figures or symbols with no context to give them meaning.
Define: information
Data that has been given context, so that it means something.
Which step do machines struggle with?
Wisdom. They can find patterns, but deciding whether acting on a pattern is right is a choice about values.
Quantitative vs qualitative data
Quantitative is numbers you can count or measure. Qualitative is words, images and sounds — descriptions.
Define: metadata
Data about other data — the time, place, device or author attached to a file rather than its content.
Why can metadata be more revealing than content?
It shows who, where, when and how often, without anyone reading a word — which is enough to map someone's life.
Kinds of data the guide names
Cultural, financial, geographical, medical, meteorological, transport, scientific and statistical.
The two uses of data the guide names
Finding trends, patterns, connections and links; and collecting measurable facts about people and communities.
Link vs cause
A link means two things move together. A cause means changing one changes the other — which needs a controlled test, not a chart.
Why is acting on a link dangerous?
The pattern is real, so the system looks right, while the reason behind it may not exist at all.
A case where a pattern repeated the past
Amazon’s scrapped CV tool learned from a decade of mostly male applications and downgraded CVs containing “women’s” (reported 2018).
The seven stages of the data life cycle
Create/collect/extract, store, process, analyse, access, preserve, reuse.
Which stage causes most argument?
Reuse — data collected for one purpose used for another the person never agreed to.
What can go wrong when data is processed?
Cleaning can drop the awkward records, so the result looks tidier and more certain than the truth.
Why does GDPR attach to purpose, not data?
Because reuse is the stage that changes what the data does to a person, so each purpose needs its own lawful basis (in force 2018).
Primary vs secondary data
Primary: collected first-hand for your own question. Secondary: collected by someone else for theirs.
What does a database do?
Organises and structures data so it is accessible, manageable and capable of being updated.
The question to ask of any dataset
Who is NOT in it? Data from app users leaves out everyone without the app.
Why is classification a choice?
The categories decide what can be counted. An answer the form does not offer can never appear in the results.
Ways to represent data
Charts, tables, reports, infographics and visualizations.
Five checks on any chart
Does the axis start at zero? What time range? Are the areas honest? Count or rate? What is missing?
How can a chart mislead without lying?
A truncated axis, a chosen start date or an area scaled in two dimensions changes what the reader sees while every figure stays true.
Why does making data visible matter?
Global Fishing Watch (2016) collected nothing new — publishing existing signals as a map moved power from fleets to the public.
The three data-security methods
Encryption (lock it with a key), masking (replace it with realistic fakes), erasure (destroy it so it cannot be recovered).
What does blockchain protect?
Whether a record has been changed since it was written. NOT whether it was true when written, and not privacy.
Delete vs erase
Deleting usually removes only the pointer; the contents stay until overwritten. Erasure overwrites the space.
Why do most breaches happen?
Ordinary controls not kept up — a reused password (Colonial Pipeline, 2021), an unapplied patch (WannaCry, 2017).
The four characteristics of big data
Volume, variety, velocity, veracity.
Which characteristic is about quality?
Veracity — whether the data is right. Volume does not fix errors, it hides them.
What analytics is used for
Predicting behaviour, modelling what would happen under other conditions, and understanding past, present and future behaviour.
Why can a bigger dataset be no fairer?
A group never collected from is still absent, so the blind spot stays while the model looks more reliable.
The three families of data dilemma
Bias, reliability and integrity; control, ownership and access; privacy, anonymity, surveillance and personally identifiable information.
Why is removing names not enough?
A few details together — postcode, date of birth, sex — identify most individuals, and joining datasets makes the link easy.
What makes something a dilemma?
The harm and the benefit come from the same cause, so removing one removes the other.
A case for each family
Quality: COMPAS. Ownership: the right to be forgotten (CJEU 2014). Surveillance: San Francisco's facial recognition ban (2019).
Define: algorithm
A set of defined steps that solves a problem or carries out a task.
The four characteristics of an algorithm
Unambiguous, finite, well-defined inputs and outputs, feasible.
How is an algorithm's effectiveness judged?
Often by efficiency — how much work it does as the size of the job grows.
Is an algorithm the same as a program?
No. A recipe is an algorithm. A program is one way of expressing an algorithm so a computer can run it.
The four components of an algorithm
Instructions, variables, conditionals, loops.
What does a conditional do?
Runs a step only if something is true — which is where decisions, and unfairness, enter an algorithm.
What does a loop do?
Repeats steps until a condition is met, applying one rule to every item — which turns a rule into a policy.
Why is a threshold never neutral?
Wherever the line falls, someone sits just the wrong side of it, and the rest of the system cannot see them.
Four ways to represent an algorithm
Natural language, flow chart, pseudocode, and code in a programming language.
Flow chart shapes
A rectangle is a step. A diamond is a decision with two ways out.
Why does the form matter socially?
It decides who can read and therefore check the rule. Code excludes almost everyone; a flow chart excludes almost nobody.
Weakness of natural language
It is ambiguous — the one thing an algorithm must not be.
Four core operations on a set
Sorting (reorder), searching (find one), filtering (remove), classifying (label).
Other uses the guide names
Prioritising, associating, counting, software development, and machine learning.
Sorting vs filtering
Sorting keeps everyone and changes the order. Filtering removes, and the removed are invisible to everything downstream.
The question that opens a counter-argument
What happens to the person at the bottom of the ranking?
The algorithmic dilemmas the guide names
Bias and fairness; accountability; transparency and black boxes; erosion or loss of human judgement.
Where does algorithmic bias come from?
The training data, who is missing from it, stand-in measures, and the target chosen — not from a biased rule.
Why is removing a protected field not enough?
Other fields stand in for it — postcode, school, a gap in work — so the model rebuilds it.
Why is transparency alone not enough?
Knowing why you were rejected is useless if nobody is obliged to reconsider. Accountability is a separate requirement.
Five types of computer
Mainframe, server, personal computer, tablet or smart phone, embedded system.
Define: embedded system
A computer built inside another product to do one job — a washing machine, a card reader, a traffic light.
Why are embedded systems a governance gap?
Nobody thinks of them as computers, so nobody asks who updates them, who can reach them, or what they record.
Client and server
Roles, not machine types. The same computer can act as either.
The four stages every computer performs
Input, process, store, output.
Hardware vs software
Hardware is the physical parts. Software is the instructions telling them what to do.
Memory vs storage
Memory (RAM) holds what is in use and empties when power goes. Storage keeps things when it does.
CPU vs GPU
A CPU does one complicated thing at a time, very fast. A GPU does thousands of simple calculations at once — which suits AI training.
Define: programming
Writing instructions in a language with a specific syntax so that a machine can carry them out.
Open source vs closed source
Open: anyone may read, change and share the code. Closed: only the owner may — but there is someone accountable.
Why is automation not neutral?
It moves a judgement from a person who could make an exception into a rule that cannot.
The question to ask about any system
Who is able to check it? That turns a software question into a digital society answer.
The five generations of computing
Vacuum tubes (1940s), transistors (1950s), integrated circuits (1960s), microprocessors (1970s on), AI and cloud (now).
What defines a generation?
The switching technology inside — each one smaller, cheaper and more reliable than the last.
Moore's observation
Components on a chip roughly doubled every two years. A prediction the industry organised around, not a law — and it has slowed.
What did the cloud reverse?
Computing had been moving closer to people; the cloud moved the processing back into a data centre and left a screen in your hand.
The three types of computing network
Wired, wireless and cloud — three layers of one connection rather than three choices.
How physical is the internet?
Around 99% of international traffic runs through undersea cables. Only the last hop is usually wireless.
Define: cloud computing
Computing rented from a provider's data centre rather than owned.
What does the cloud move out of your control?
Where the data physically sits, which country's law applies, and whether the service exists tomorrow.
The six network components
Client, server, modem, router, switch, hub.
Switch vs router
A switch connects devices within one network. A router passes traffic between networks and chooses the path.
Switch vs hub
A switch sends each message only to its destination. A hub sends everything to everyone — slower and less private.
Client and server
Roles, not machine types. Whatever asks is a client; whatever answers is a server.
Bandwidth vs latency
Bandwidth is how much data passes per second. Latency is the delay before the first data arrives.
Define: protocol
An agreed set of rules for how machines communicate — how to start, how to send, how to report an error.
Why do open standards matter?
The rules are public, so anyone can build equipment that joins the network — which is why no company owns the internet.
Why is network reliability double-edged?
Routing around damage makes a network hard to break by accident and hard to censor on purpose. The same property.
ISP services other than web access
Email, hosting, cloud storage and backup, phone service, domain names, filtering.
What can an ISP see?
Which sites you reach and when — the pattern — even where the contents are encrypted.
Why are providers a point of control?
Everything passes through them, so courts, governments and rights-holders all enforce through them.
The judgement line on provider power
The power is unavoidable — someone runs the wires — so the question is whether its use is visible and appealable.
Internet vs World Wide Web
The internet is the global network of networks. The web is ONE service on it — linked pages fetched by a browser using HTTP.
Key dates
Internet: ARPANET 1969, TCP/IP 1983. Web: proposed 1989, public 1991.
How to tell whether something is the web
If a browser and a page are not involved, it is not the web.
Why the distinction matters
Blocking a website touches one service. Shutting off the internet touches everything. They are different measures.
Web 1.0, 2.0 and 3.0
1.0: a few publish, everyone reads. 2.0: users make the content, platforms own the place. 3.0: contested — semantic, or decentralised.
Early internet milestones
ARPANET 1969, TCP/IP standardised 1983, the web proposed 1989 and public 1991.
What Web 2.0 made private
Moderation. What may be said became a company policy rather than a law.
The judgement line on the web and power
Power to speak widened enormously; power to decide what is heard narrowed to a few companies.
The internet dilemmas the guide names
Privacy, anonymity and surveillance; the right to be forgotten; the digital divide; freedom of expression and censorship.
What makes something a dilemma?
The harm and the benefit come from the same property, so removing one removes the other.
The right to be forgotten
Google Spain v AEPD, CJEU 2014 — search results may be de-listed where inadequate, irrelevant or excessive. The page itself stays.
Why is online censorship usually partial?
A network built to route around damage treats blocking as damage, so material reappears by another path.
Types of digital media
Text, images, audio, animations, video and web pages.
Define: synthetic media
Content generated rather than recorded — synthetic text, voice, images or video.
Why is synthetic media hard to regulate?
It is not a new form but a new origin for every existing form, so any rule about it touches all of them.
Why does video dominate?
It demands the most attention and therefore holds it longest, and engagement-based ranking promotes what holds attention.
Characteristics of digital media
Rapid sharing, efficient storage, interactivity, linear and non-linear paths, perfect copying.
Linear vs non-linear media
Linear runs in one order set by the maker. Non-linear lets the audience choose a path — from options someone else decided.
What did interactivity change?
Responses can be recorded, which turned an audience into a dataset.
Why does a correction not catch the claim?
Non-linear media means nobody sees the same sequence, and a duller correction is shared less and ranked lower.
AR, VR and MR
AR adds a layer over the real world. VR replaces it entirely. MR lets virtual and real objects interact.
Professional uses of immersive media
Surgical rehearsal, aircraft maintenance, emergency response training, empathy exercises.
What does a VR headset measure?
Where the user looks and how they move — more intimate than a click.
The judgement to reuse
Ask what the technology is used INSTEAD of, not whether it works.
The four families of media dilemma
Psychological concerns; truth and synthetic media; ownership and plagiarism; representation and moderation.
Misinformation vs disinformation
Misinformation is false and shared without intent to mislead. Disinformation is false and spread deliberately.
Why does a correction not catch the claim?
It is duller, so it is shared less and ranked lower — the same mechanism that spread the claim suppresses its correction.
The strongest judgement on platform responsibility
Responsible for what they AMPLIFY rather than for everything posted, because ranking is the part they choose.
The three levels of AI
Narrow (weak, domain-specified) — one task, and all that exists. General (strong, full) — any human task, does not exist. Super-intelligent — hypothetical.
Does “weak AI” mean it performs badly?
No. Weak describes the RANGE of tasks, not the quality. A weak AI can beat every human at its one task.
The Turing test (1950)
If a person cannot tell a machine from a human in conversation, it passes. It tests convincing, not understanding.
The trap to avoid
Arguing from general AI. Real questions are about narrow systems doing exactly what they were built for.
The three kinds of machine learning
Supervised (labelled examples), unsupervised (no labels, finds groups), reinforcement (a goal and a score).
Is deep learning a fourth kind?
No — it describes many layers in the network, and can be supervised, unsupervised or reinforcement.
Uses of machine learning the guide names
Pattern recognition, facial and speech recognition, image analysis, natural language processing.
Where bias enters a model
The labels, who is missing from the data, stand-in measures, and the target chosen.
What is a neural network?
Layers of simple units joined by weighted connections. Numbers in, numbers out; training adjusts the weights.
What are neural networks good at?
Modelling complex, non-linear relationships, and generalising from their training to inputs they have not seen.
Why is a trained network a black box?
It holds millions of weights, not rules. There is no line to point at and no sentence to read out.
The word to avoid
“Thinks”. Say it models a relationship — the guide's own wording, and it keeps the answer defensible.
What is an AI winter?
A period when the promises outran the results and funding was withdrawn. There have been two: the 1970s and the late 1980s.
Why did expert systems fail?
They captured what an expert SAID, not what an expert noticed, so they broke on the first case outside the rules.
Why is now arguably different?
Learning from data removes the cause of both winters — nobody has to write the exceptions down.
The judgement to reuse
The method is genuinely different; the expectations are not — and it is expectations that have collapsed before.
The AI dilemmas the guide names
Fairness and bias; accountability; transparency; uneven and underdeveloped regulation; automation and displacement.
Why is fairness not a followable instruction?
Competing definitions — equal accuracy across groups and equal error types across groups — cannot both hold except in special cases.
What shape does AI regulation take?
Mostly about USE: who may deploy it, for what, with what duties — as in the EU AI Act's high-risk categories.
The judgement lines to reuse
“Prompt, not decision” for automated decisions about people; “responsible for what it amplifies” for platforms.
Three kinds of robot
Industrial (repeats a path, caged), service (works among people), social (interacts with people as its purpose).
Autonomous technologies the guide names
Internet of things, autonomous vehicles, drones, virtual assistants.
Is a surgical robot autonomous?
The da Vinci system is teleoperated — a surgeon moves the instruments through a console. It augments rather than replaces.
The axis underneath every example
How much the machine decides for itself, from a caged arm that decides nothing to a vehicle deciding continuously.
The characteristics of robots and autonomous technologies
Sensory inputs for spatial, environmental and operational awareness; reasoning with machine vision and learned models; acting physically; some degree of autonomy.
The three kinds of awareness
Spatial (where am I), environmental (what is around me), operational (how am I doing).
The sentence that answers 'why did it fail?'
A machine cannot react to what it has no sensor for.
Why is acting different from recommending?
A recommendation can be ignored. A movement has already happened and cannot be un-made.
How robots developed
Mechanical automata → caged industrial arms (1960s) → sensing robots → service robots among people → autonomous systems deciding.
How was early robot safety achieved?
By separation — keeping people out of reach — not by the robot noticing them.
What let robots leave the cage?
Sensing. A machine that can detect a person can slow down or stop for them.
What makes autonomous vehicles ethically distinct?
The pedestrians and cyclists sharing the risk never consented, where a factory worker did.
The robot dilemmas the guide names
Anthropomorphism and the uncanny valley; responsibility for harm; safety; employment and displacement; surveillance.
Define: the uncanny valley
Comfort rises as a machine becomes more human-like, drops sharply when it is almost-but-not-quite, then rises again.
Define: anthropomorphism
Treating a machine as though it has feelings and intentions — which people do readily and designers encourage.
The question to ask in any robot essay
What is the machine funded INSTEAD of? It turns a technology answer into a social one.
What digital systems changed in the arts
Publishing became free; being heard became a ranking decision rather than a person's.
Why did reach and income separate?
The platform sets the payment per play, so a large audience no longer produces a large income.
The invisible cost of a ranking
The work that was never made because it would not have suited the system.
BookTok as change and continuity
Readers now decide what sells — but the publisher still prints it and still takes most of the money.
What connected home devices send
Routine rather than content — when you are in, what you watch, how you sleep.
Why is routine data more valuable?
It predicts behaviour, and it does not feel private, so almost nobody objects to it being collected.
What remote work removed
The journey home — the boundary that ended the working day and that nobody had to maintain.
A home device with a real clinical benefit
Watches that detect an irregular heart rhythm a yearly check would miss entirely.
What survives digitization
Appearance, text and sound — and the record survives fire, flood and war.
What does not survive digitization
Who may see it, when it may be performed, what presence means — rules held by a community, not properties of the object.
The real heritage question
Not whether to digitize, but who holds the copy and whether the source community can still say no.
Heritage + power
Once the copy is published, the community that set the rules about access no longer decides.
Why online subcultures can form
People too rare to meet in one town are one search apart once distance stops limiting who finds whom.
Why subcultures break at scale
The ranking brings in people who do not know the group's rules, faster than it can absorb them.
One mechanism, both outcomes
Easy discovery builds support groups and harmful groups alike — it is one property producing both.
The defensible position on harmful groups
Limit amplification rather than existence: stop recommending, do not stop allowing.
The four digital business models
Sell it once, subscribe, advertising, commission.
Why does 'free' change a product?
The advertiser is the customer, so the product is built to hold attention rather than to be useful.
Define: platform business
A business that provides the place where two other groups trade, takes a share of each transaction and sets the terms.
Why one dominant platform per market?
Each side is there because the other is, so a competitor has to attract both at once.
Tasks, not jobs
Automation takes tasks out of a job rather than removing the job — the job that remains is a different job.
What decides which tasks go first?
Predictability, volume, how cheap an error is, and whether the data already exists.
Why are skilled tasks vulnerable?
Skilled tasks are often predictable and richly recorded — reading a scan is easier to automate than clearing a table.
The hidden loss in automation
Entry-level tasks were how people learned the job, so removing them removes the route into the field.
Why is money a hard digital good?
Digital things copy; money must move. Spending has to remove it from the sender.
The two ways to keep digital money honest
One organisation holds the record, or thousands of copies of one shared record are held.
The real trade in digital currency
Control by an organisation you can appeal to, against control by a rule that cannot be appealed to.
Why mobile money reached the unbanked
It used phones people already owned, so it needed no new branches or infrastructure.
What made long supply chains possible
Digital coordination became nearly free, payment became immediate, and demand became visible everywhere at once.
Where value is captured
At design and at the sale — the two steps involving the fewest people.
Where cost lands
At mining, assembly and disposal — the steps furthest from where the profit is recorded.
Why national rules miss global harm
The government with the power to act has no harm in front of it, and the one with the harm has no hold over the company.
The two halves of digital and the environment
Digital systems reveal harm at enormous scale and consume electricity, water and mined metals to do it.
What monitoring adds
Scale, continuity over time, and observation where no inspector would be allowed.
Why monitoring often changes nothing
Evidence only works where an authority has both the power and the will to act on it.
The test for a monitoring system
Did anybody decide differently because of what it showed?
The four stages of a device's life
Mined, made, used, discarded — owners see only one of them.
Which stage dominates the footprint?
Making it. For a phone, manufacturing produces far more emissions than using it ever will.
Why lengthening life beats recycling
Recycling acts after the emissions have happened; a longer life means they happen less often.
What completes a right-to-repair rule
A guaranteed minimum period of security updates alongside the spare parts.
The smart-city loop
Sense, decide, adjust — continuously, without waiting for a budget cycle.
Who a sensor network misses
People walking, people without phones, and areas that were never instrumented.
Why automatic adjustment resists challenge
There is no meeting and no decision to point at, so residents have nothing to appeal against.
Connection as a risk
What makes infrastructure efficient makes it reachable — a pipeline shutdown stopped fuel for a region with nobody touching a pipe.
What precision agriculture does
Measures variation within a field so seed, water and fertiliser go only where they are needed.
Why it is a strong environmental example
It reduces an input while holding the output, rather than moving a harm somewhere else.
What comes with the gain
Field data and repair rights both move to the machine's manufacturer.
The fix worth recommending
Rules giving the farmer the data and the right to repair — separating the environmental gain from the loss of control.
The five steps of a patient's path
Symptom, access, triage, diagnosis, treatment — digital systems have entered all five.
The key health question
Does the system propose to a person, or does it decide? An error in the second has no owner.
Why triage is the hardest case
An error is a person waiting, and nobody sorted downwards is told they were sorted.
Why overall accuracy misleads
It hides much worse performance for groups barely present in the training data.
Four levels of technology and the body
Carried, worn, implanted, and reading the nervous system.
Why consent weakens down the ladder
Refusing costs more at each level — at the bottom it costs your health, so agreement is formal rather than real.
Why body data is different
It cannot be changed, is collected continuously, and reveals illness, pregnancy and mood.
What protects better than consent
Limits on what may be collected at all, because a limit does not depend on the person's bargaining position.
Why two rising lines prove little
The cause may run either way, or a third factor may move both.
Why averages mislead here
A large effect on a small group disappears into a small average — and that group is the concern.
Mechanisms worth naming
Comparison, disturbed sleep, harassment that follows a person home, and targeted content.
Why the narrow claim is stronger
It names something a platform could change, so refusing to change it becomes the thing to judge.
The four jobs of teaching
Delivering, practising, noticing who is lost, making somebody want to continue.
Which jobs move online?
Delivering and practising move well; noticing and motivating barely move.
Why do the same two fail?
Both depend on a relationship with a particular person, which no system supplies.
Why free is not equal
What surrounds the tool — a device, a quiet hour, somebody to ask — decides who finishes.
The five steps of making knowledge
Ask, gather, analyse, check, publish.
Which steps collapsed in cost?
Gathering and analysing — and publication became immediate.
Why is checking the bottleneck?
It takes the same work it always did and nobody is rewarded for doing it, so results outran verification.
What makes checking cheap
Publishing the data and the code, and registering the method before the data is examined.
What broadcasting provided
A shared message that opponents and journalists could check — the accountability came with the inefficiency.
Why targeting resists scrutiny
Each message is seen only by its group, so promises cannot be placed side by side.
What an advert archive restores
Visibility — anybody can see what was said to whom, without restoring the shared audience.
Participation against visibility
Participation tools are optional and small; scrutiny losses reach every voter, including those who use none of these tools.
What digital government does well
Available at any hour, identical for everybody, much cheaper, and traceable.
What it removes
The official who could see that a case was unusual and do something about it.
Why one identity record is risky
It becomes the key to everything, so a single exclusion removes access to many services at once.
The condition for a defensible digital service
A real, reachable route to a person who can decide differently.
Four forms of digital conflict
Infrastructure attacks, information attacks, autonomous weapons, and dependence on private infrastructure.
Why attribution is central
Every rule about conflict assumes you know who acted, and digital conflict is designed to be deniable.
What is new about autonomous weapons
A wrong selection has no person whose decision it was, so no one can be held responsible.
The private infrastructure problem
A company's commercial decision about service coverage can become a military decision — an arrangement no rule anticipated.
Why law is always late
A rule can only be written after a harm appears and is measured, and each step takes years.
Three ways to write a technology rule
Name the technology, state principles, or sort by the risk of the use.
Why risk tiers work better
They govern by use rather than by name, so a system invented tomorrow is covered the day it is used for a risky purpose.
When does a rule actually bite?
When the market is worth more to the company than the cost of complying — which makes reach a function of market size.
The four steps of online group identity
Find each other, get shown more, define against another group, stop meeting them.
Which step is changeable?
What the system rewards — hostility holds attention, so the ranking favours the version with an enemy in it.
The defensible claim about division
Platforms amplify division rather than cause it — narrower, better evidenced, and it points at a specific fix.
Why finding each other is a gain
People whose group is rare where they live gain both practical knowledge and recognition.
The three digital divides
Access (do you have it?), use (what can you do with it?), outcome (what do you get from it?).
Why access alone is not enough
The gap is produced by what surrounds the tool — a device of your own, quiet time, somebody to ask.
Why device programmes under-deliver
They close the first divide, which is also the one that gets measured, and leave the other two.
The difference that compounds fastest
Having somebody to ask — being stuck ends one student's session and costs another three minutes.
What crosses a distance
Words, faces, news and arrangements — enough to stay informed and be present for big events.
What does not cross
Ordinary unplanned time, which is where close relationships are actually maintained.
What monitoring costs
Being trusted — which is how a young person learns to make a decision nobody will check.
The condition for defensible monitoring
Agreed rather than hidden, with a stated end — covert monitoring loses the safety benefit the moment it is found.
