A job is a bundle of tasks, not a fixed role. When email replaced typewriters, secretaries didn't disappear; they shifted to travel planning and events. AI will change what people do, not necessarily eliminate the jobs themselves.

The way the economists think about it is a job is a bundle of tasks. Everybody wants to talk about job loss, but really what you want to look at is task loss. The classic example of task changing was once upon a time, executives never used typewriters or personal computers themselves. You had a secretary who you dictated memos to. And then there was this change where like emails started to show up. The job of the secretary then went from sending out letters with stamps on them to like sending and receiving emails with the other admins. Fast forward to today. None of that happens now. Executives just do all their own email. They still have stamps, secretaries or admins, but they're now doing different tasks. They're travel planning and orchestrating events and like doing all these other things. The executive job still exists, the secretary job still exists, but the tasks have changed. The job persists longer than the individual tasks.
