Yeah I agree with that, that's why I specified knowledge workers. I don't think it's bad if cashiers get replaced by self-checkout or if receptionists get replaced by automated agents on either end.

Emergency/police dispatchers - obviously increased sensitivity that makes it a special case, but I still think AI can eventually do the job better than a human.

Driving cars - not yet, at least not outside specific places, but probably eventually, and definitely for known routes.

Teaching yoga - maybe never, as easy as it would be to do, some people might always want an in-person experience with a human teacher and class.

But importantly - most knowledge workers can't be displaced by AI when the work entails solving problems with undocumented solutions that the AI could not have trained on yet, or any work that involves judgment and subjectivity, or that requires a credential (doctor to write the prescription, engineer to sign off on the drawing) or security clearance, authorizations, etc. There's a lot of knowledge work it can't touch.
