Why This Page Exists

The Ethics of Machine Learning page asks whether a particular system is fair, safe, and accountable. This page zooms out to a different question: what happens when computing stops being something you use and becomes something you live inside?

Computers are no longer boxes on desks. They are in your pocket, your watch, your doorbell, your car, your school gate, and the infrastructure of your city. Each device is convenient on its own. Taken together, they change daily life: how you are watched, what work exists, who has access, and where the line between public and private sits. The technology often arrives faster than the rules for using it.

This page is about those society-wide effects, and about a habit of mind the syllabus asks you to develop: continually reassessing ethical guidelines as technology advances, because last year’s rules were written for last year’s technology.

Pervasive and Embedded Computing

A computer is embedded when it is built into a larger device to do one job (the chip in a washing machine, a pacemaker, a traffic light). Computing is pervasive (or ubiquitous) when so many embedded and networked devices surround us that computing fades into the background of ordinary life.

The convenience is real: a smart thermostat saves energy, a fitness tracker flags a heart problem, a connected car routes around a traffic jam. The ethical weight comes from three features of pervasiveness:

It is always on. A device that is always sensing is always able to collect data. A smart speaker that listens for a wake word is, in principle, listening.
It is hard to opt out of. You can choose not to buy a smart doorbell, but you cannot choose whether your neighbour’s smart doorbell records you on the pavement. Pervasive computing affects bystanders who never agreed to it.
The data combines. Each device’s data seems trivial alone. Linked together (location, purchases, search, movement, voice) they form a detailed picture of a person’s life that none of the individual devices implied.

Example: A “smart city” deploys connected sensors, cameras, and number-plate readers to manage traffic and lighting efficiently. The same infrastructure can track where any individual goes and when, even though no resident consented to being followed.

Surveillance, Privacy, and Individual Rights

When sensing is everywhere, surveillance becomes the default rather than the exception, and the question shifts from “is this person being watched?” to “who is watching everyone, and what may they do with it?”

The ethical tension is genuine and runs in both directions:

Surveillance technologies can prevent crime, find missing people, and keep infrastructure safe.
The same technologies can chill free expression (people behave differently when they know they are watched), enable abuse of power, and erode the individual rights to privacy and freedom of movement.

A useful distinction is between targeted surveillance (watching a specific person for a specific, justified reason, ideally with oversight) and mass surveillance (watching everyone by default in case something is found later). Most ethical objections concentrate on mass surveillance, because it treats an entire population as suspects and creates a store of data that can be misused long after it was collected.

Privacy in daily life is not just about secrets. It is about context: information you share willingly in one setting (a medical detail with a doctor, a location with a friend) can cause harm when it flows into another (an insurer, an employer, a stranger). Much of the privacy harm from pervasive computing comes from data leaving the context it was given in.

Note for IB CS learners: the strongest “Discuss” answers on surveillance avoid an absolute position. “Surveillance is always wrong” and “if you have nothing to hide you have nothing to fear” are both weak. The high-mark move is to weigh a real benefit (a named safety gain) against a real cost (chilling effect, data misuse, lack of consent) and conclude under what conditions and oversight the trade-off is acceptable.

Equity and the Digital Divide

The digital divide is the gap between those who have good access to computing and the internet and those who do not. As more of daily life moves online (banking, government services, education, job applications, healthcare bookings), being on the wrong side of the divide stops being an inconvenience and becomes exclusion from ordinary life.

The divide has several layers, and a strong answer names which one is in play:

Access – do you have a device and a reliable connection at all? This splits along income, and between richer and poorer regions and countries.
Affordability – even where infrastructure exists, data and devices may cost too much.
Skills – having access is not the same as being able to use it safely and effectively (digital literacy).
Quality – a slow, capped mobile connection is not equivalent to fast home broadband, even though both count as “access.”

Equity is the goal of fair access and fair outcomes, which is not the same as treating everyone identically. A service that is only usable on an expensive new phone is formally “available to everyone” but is not equitable. When a government moves a service online and removes the offline alternative, it can unintentionally cut off the people who most depend on it.

Example: A country moves welfare applications to an online-only system to cut costs. The change works well for most people and excludes exactly the low-income, elderly, and rural applicants who most need the support and are least likely to have reliable internet access.

Emerging Technologies

The syllabus names three emerging technologies whose societal effects are still unfolding. The ethical skill here is not to predict the future but to reason about what new questions each technology raises before it is everywhere.

Pervasive AI

When AI assistants, generators, and decision systems are woven into daily life (writing, tutoring, hiring, medical triage, customer service), the concern is less any single model and more the cumulative effect: over-reliance and deskilling (people losing abilities the AI now does for them), concentration of power in the few organisations that own the largest models, and the difficulty of telling human-made from machine-made content. All nine dimensions from the machine learning ethics page apply, but at the scale of a whole society rather than one system.

Augmented and Virtual Reality (AR / VR)

AR overlays digital content on the real world; VR replaces it. Both depend on intense sensing of the user: where you look, how you move, your surroundings, sometimes your physiological responses. This makes them privacy-intensive in a new way (eye-tracking can reveal attention and emotion), raises questions about consent of bystanders captured by AR cameras, and introduces concerns about psychological effects, addictive design, and the blurring of real and simulated experience, especially for young users.

Quantum Computing

Quantum computers exploit quantum physics to solve certain problems far faster than classical machines. The headline ethical issue is security: a sufficiently powerful quantum computer could break much of the encryption that currently protects banking, messaging, and stored data. This drives the move toward post-quantum cryptography. A second issue is equity: if quantum computing delivers a decisive advantage, whoever gets there first (a state or a corporation) could gain disproportionate power. Because the technology is genuinely new, there is very little settled ethical guidance for it, which is precisely why the next section matters.

Reassessing Ethical Guidelines as Technology Advances

This is the idea that ties A4.4.2 together. Ethical guidelines, laws, and norms are written for the technology that exists when they are made. Technology then moves on, and the old rules either fail to cover the new situation or actively get it wrong.

Privacy law written for paper records struggles with data that can be copied, combined, and inferred from instantly.
Copyright rules written for human authors did not anticipate models trained on millions of works.
Encryption standards considered unbreakable for decades may not survive quantum computing.

The ethical response is not to write one perfect rulebook and stop. It is to treat guidelines as living documents that are reviewed as the technology changes, informed by the people affected, and updated before harm becomes widespread rather than after. This is genuinely hard: the law is slow and deliberate by design, while technology is fast, so there is always a gap. Recognising that gap, and arguing for how to narrow it, is itself a strong ethical position.

Example: When generative AI made convincing fake video cheap, existing laws on defamation and fraud were not written with deepfakes in mind, leaving victims with weak protection until rules were revisited. The lesson is not that the old laws were stupid; it is that they could not anticipate the technology, so they had to be reassessed.

Work and Society

Two further society-wide threads recur whenever computing integrates deeper into daily life.

The changing workforce. Automation and AI remove some jobs, change many, and create others. The honest framing is not “robots take all the jobs” but a two-population question: those whose work is automated away and need retraining and support, and those who benefit from the new, often higher-skilled roles. A fair transition is a policy and ethical question, not just an economic one: who bears the cost of the change, and who captures the gains?

Globalisation and jurisdiction. Networked computing lets services, data, and work flow across borders instantly. This spreads opportunity, but it also means a person’s data may be stored and processed under the laws of a country they have never visited, with weaker protections than their own. When something goes wrong, it can be unclear whose rules even apply.

How to Answer a “Discuss” Question

Like A4.4.1, A4.4.2 is examined with the command term Discuss: a balanced, reasoned argument that reaches a conclusion. The structure is the same:

One side – the genuine benefits of the technology or change, each point developed.
The other side – the genuine costs and risks, named precisely (privacy, equity, individual rights, surveillance) and developed.
A reasoned conclusion – a defended position that weighs your own points and, for these society-scale questions, usually states the conditions or safeguards under which the benefit outweighs the cost.

For daily-life questions specifically, the strongest answers resist absolute positions. Pervasive computing, surveillance, and emerging tech all carry real benefits and real harms at once. A calibrated “yes, but only if…” or “the benefit holds for most people while excluding a vulnerable minority, so…” outperforms a flat verdict every time.

The checklist for a top-band response: detailed, accurate knowledge; correct terminology used throughout (name the actual concepts: digital divide, mass vs targeted surveillance, individual rights, equity); balanced analysis of more than one side; and a conclusion clearly linked to that analysis.

Quick Check

Q1. You can choose not to buy a smart doorbell, but you cannot stop your neighbour's smart doorbell from filming you on the pavement. This best illustrates which feature of pervasive computing?

Q2. A system records the movements of every citizen in case the data is useful later. How is this best described, and why is it the more controversial form?

Q3. A government replaces an in-person benefits service with an online-only system. Which concern is most directly raised?

Q4. Which is the most commonly cited ethical/security concern about powerful quantum computers?

Q5. Laws on fraud and defamation were not written with deepfakes in mind, leaving victims poorly protected until the rules were revisited. What general principle does this illustrate?

Q6. What is the most balanced way to frame the effect of automation on work?

Practice Exercises

Note for IB CS learners: A4.4.2 is examined with the Discuss command term, so the higher-mark questions are Discuss prompts requiring a balanced argument and a conclusion. At least one question asks for a full prose response.

Core

Define (4 marks) – Define the digital divide and outline two distinct layers of it (for example, access and skills), with an example of each.
Distinguish (4 marks) – Distinguish between targeted and mass surveillance, and state why mass surveillance attracts more ethical objection.
Explain (4 marks) – Explain why pervasive (always-on, networked) devices raise privacy concerns that a single offline device does not.

Extension

Explain (6 marks) – Explain what it means to treat ethical guidelines as “living documents,” using one example of a technology that outpaced its existing rules.
Discuss (8 marks) – A city proposes covering its public spaces with connected cameras and sensors to create a “smart city.” Discuss the ethical aspects of this integration of computing into daily life. (Write in prose. Cover privacy, equity or individual rights, and at least one further concern, and reach a reasoned conclusion.)

Challenge

Discuss (10 marks) – A national government plans to deliver all public services (tax, health bookings, welfare, voting registration) through a single online platform. Discuss the ethical aspects, weighing efficiency and access against the digital divide, surveillance, and individual rights. Reach a calibrated conclusion stating the safeguards required.
Evaluate (10 marks) – As AR and VR move into everyday education and work, evaluate the claim that their benefits to learning and productivity outweigh their costs to privacy and psychological wellbeing. Recommend a position and justify it.
