Cory Doctorow is a science fiction novelist, journalist and longtime digital-rights activist, and the writer who named enshittification. In this book he turns the same kind of analysis on the AI boom. He argues that the useful question about any technology is not only what it does, but who it is for and who it is done to. His central image is the centaur, a person helped by a machine, and its opposite, the reverse centaur: a person drafted in to serve a machine at the machine's pace, like the delivery driver with no time for breaks or the programmer asked to check more code than anyone could. He reads much of the AI hype as a story told to investors to keep big tech firms priced as growth companies, and warns that the money behind it looks like a bubble. He is not against AI itself, says it helps in some of his own work, and asks what useful tools should be left standing when the bubble goes.
The reverse centaur is not new. Doctorow reaches back to Lucy and Ethel on the speeding chocolate line in I Love Lucy: the belt sets the pace, and the people scramble to keep up. What AI adds is speed and scale, and a new place to put the person: in the loop, signing off on the machine's work faster than anyone could check it.
So he skips both the cheerleading and the doom. The same tool, he argues, can make one worker faster and freer and grind another one down. The difference is who controls it and who pays for its mistakes.
Pillar 1
The centaur
A person with a machine as an assistant. Doctorow's own example is his car's lane-drift warning: it helps, and he is still the one driving.
Pillar 2
The reverse centaur
A person drafted in as the machine's assistant: the delivery driver watched and scored by apps, or the specialist kept on to sign off on a machine's output faster than anyone could check it.
Pillar 3
The bubble
Hype aimed at investors keeps big tech priced as a growth story. Doctorow expects it to burst, and asks which useful tools we want left standing afterwards.

From hype to human
The chain as Doctorow describes it, in five links.
The growth storyMarkets pay a premium for growth. A giant whose markets are full needs a new frontier to keep it.
The pitchAI is sold as a way to replace well-paid work, because nothing smaller pays back the money being spent.
The reverse centaurThe job is not replaced. A person is kept in the loop to check the machine's output at the machine's pace.
The accountability sinkWhen the machine gets it wrong, the person who signed off takes the blame. The term is Dan Davies's.
After the bubbleSpending runs far ahead of revenue, and bubbles burst. Some useful tools survive. Which ones, and on whose terms, is the open question.
Community insights
What readers take from it.
No. 01HourLife takeaway
Ask who a technology is for and who it is done to, not only what it does.
Doctorow says he took this habit from science fiction, where the interesting part of a gadget is the society around it. A feature can be the same code in two workplaces and mean opposite things, depending on who controls it and who carries the cost. The two questions run through every chapter.
No. 02HourLife takeaway
A centaur rides the machine. A reverse centaur is ridden by it.
In automation theory a centaur is a person with a machine as an assistant. Doctorow contrasts the lane-drift warning in his own car, which he can turn off, with an Amazon delivery driver juggling several apps and scored by software. Same kind of technology, but only one of them is in charge.
No. 03HourLife takeaway
The human in the loop is often there to take the blame.
Doctorow borrows the idea of an accountability sink from the writer Dan Davies. A person signs off on the machine's output at a speed no one could check properly, and when the machine misses something, the person is the one held responsible. His example is a radiologist reviewing scans an AI has already read.
No. 04HourLife takeaway
Much of the AI pitch is written for investors, not for users.
Markets pay more for a company they see as growing than for a mature one that is merely profitable. A big tech firm whose main markets are full needs a new growth story to keep that premium. Doctorow reads the AI boom, like the earlier metaverse push, as that story.
No. 05HourLife takeaway
An AI may not be able to do your job, but a sales pitch can still convince your boss it can.
The risk to workers is not only what the software can do. It is what managers are told it can do. Doctorow points to firms that swapped people for chatbots or automation and then had to deal with the results.
No. 06HourLife takeaway
The numbers behind the boom only add up if AI replaces well-paid work.
The sums invested are so large that cheap help with small tasks cannot pay them back. So the pitch aims at high-wage jobs, such as radiologists and software developers. Doctorow argues that this is mostly a fantasy, but one that can still reshape those jobs for the worse.
No. 07HourLife takeaway
Warnings that AI could end the world can work as advertising.
If a product is powerful enough to be dangerous, it must be powerful enough to be worth buying. Doctorow suggests that doom talk helps cast AI firms as the disruptors who will capture the future, which is what investors want to hear.
No. 08HourLife takeaway
Bubbles burst, and they leave things behind.
Doctorow notes how few AI products make money and how much is being spent on data centres, and compares the moment to the dot-com bubble. When that bubble popped, people kept useful things it had paid for. The question he asks is what we want to be left with this time.
No. 09HourLife takeaway
The fight is over who holds the reins, not over the machine.
Doctorow is neither an AI hater nor someone who thinks its takeover is inevitable. He describes uses that help, including in his own work. His case is that the same tool can lift a worker or grind one down, and that the difference comes from who decides how it is used.
Action steps
Take the reins back, one tool at a time.
Set up once
01
List the machines you work with
Write down every AI or automated tool you touch at work this week. For each one, note who chose it, who sets its pace, and whether you can switch it off.
02
Ask who answers for its mistakes
Pick the tool you lean on most. Ask your manager in writing who is accountable when it gets something wrong, and what you should do when you disagree with it.
03
Find out what it records about you
Ask what the tool logs about your work, who can see it and how long it is kept. Write the answer down with the date.
04
Write a one-page use policy for yourself
List the tasks where AI helps you think and the tasks you will keep doing yourself, with one line on why. Keep the page where you work.
05
Compare notes with two coworkers
Ask two colleagues how the same tool changed their pace and workload. Notes from three people are harder to wave away than one complaint.
Keep doing
06
Ask the two questions before you adopt anything
Before you switch on a new AI feature, ask who it is for and who it is done to. If you cannot answer the second, wait a week.
07
Keep a Friday error log
Each Friday, note the tool's mistakes you caught and how long fixing them took. It shows the real cost, and it is a record if blame lands on you.
08
Do one task the long way
Once a week, do something the tool usually handles without it, so the skill stays yours.
09
Read AI news for its audience
When a big AI announcement goes by, ask who it was written for: users, bosses or investors. Decide that before you share it.
One line to keep
A good tool follows your lead. If you are the one keeping pace, ask who is riding whom.
