Well, I'm too lazy to look up how many weavers were displaced back then and that's why I said a lot. Maybe all of them, since they weren't trained to operate the new machines.
Anyway, sorry for a digression, my point is LLM replacing white collar workers doesn't necessarily imply it's generally intelligent -- it may but doesn't have to be.
Although if it gets to a point where companies are running dark office buildings (by analogy with dark factories) -- yes, it's AGI by then.
