Weak AI is good enough to sorta replace workers, in areas where accuracy is not super important (customer-facing stuff, where people are already used to corporations providing minimal/poor service).

If you train your customers to accept less and less every year, then eventually replacing an underpaid, poorly-trained human with a weak AI is not going to change much except save money. AI is going to end up in places C-levels already didn't care about and were strangling.

Very true. However, weak AI is more about task automation and less about replacing human minds. Large segments of transportation will be replaced by weak AI. I think task AI will replace many jobs and augment many others.
