The print edition of this book drew a line around what machines could never do. Some of that line has already moved. This chapter tests every “AI cannot” claim, puts a date on each, and finds what stays when the skills are matched.

A machine found the spot on the X-ray that the radiologist missed. Nobody was fired. Three posts will simply never be filled. Replacement rarely looks like a machine taking your chair. Usually it is a chair that is never offered.

Nothing is more useful than water, Adam Smith wrote, and nothing buys less. Intelligence is moving from diamond to water. Its price is falling fast. Its usefulness is not. Your wage was tied to the price, and your worth never was.

A machine read an X-ray in four seconds and found what a radiologist had missed. Nobody was fired. Part II asks what the machine is, what it replaces, what it cannot, and how far to believe it, with a date on every claim.

In 1930 Keynes wrote a letter to his grandchildren about a disease called technological unemployment. The letter was addressed to us. If a machine can do what you do, what are you? The terms are being set now.

A machine can now show judgement, taste, patience, even empathy. So what makes a quality yours? Aristotle and Patañjali give one old answer: a path is made by walking it. Answering for where it leads is one more step.

Eight old traditions disagree about what a self is. Vedānta finds a witness; the Buddha would not say there is a self at all. Yet each has its own way of holding a person to what they do. A machine can do the work. It cannot take the account.

A machine tested in eleven minutes what took Priya’s team a week, and found bugs they had missed. That evening she signed a release she could not check. Machines can check their own work now. Only a person can make a decision theirs.
