Last week, Jack Dorsey, a co-founder of Twitter, announced that his company Block is cutting its head count from 10,000 to fewer than 6,000 because AI tools mean it needs fewer workers. It is not the first company to make such an announcement, and won’t be the last. But it raises a question: if AI takes jobs, are workers doomed? To many observers, the answer must be yes. Negative consequences for the labor force seem like an inevitable byproduct of advancing AI.
