Bill Gates has spent the past year warning that this wave of automation is different — that artificial intelligence replaces human thinking itself, faster than any previous technology gave workers time to adjust. On Aug. 26, 2026, he laid out his answer in a nearly 6,000-word essay on Gates Notes, in two parts: tax AI tokens and robots the way a human paycheck is taxed, and carve out a category of jobs — “Human Reserved,” capped at 40% of the workforce — that society deliberately keeps for people even where a machine could do the work just as well.

Gates offers a vivid reason: a robot could technically deliver a cancer diagnosis, he writes, but it shouldn’t. He has personal reason to feel this — his father spent 13 years in decline from Alzheimer’s, and Gates has written movingly about how much the quality of that caregiving mattered. It is a sincere, humane argument. It is also, as economic policy, a mistake.
