Q.  But to sum up, you think that AI is definitely not the issue we should be talking about with respect to unemployment.

A.  Right.  From an economic perspective, AI is a completely odd place to focus your concern about modern-day unemployment.

Interesting, I read the White House report on AI as saying it will soon replace millions of jobs:

On the other hand, agreeing with your point:

Well sure, but do they have a theory on why the economy suddenly can't replace jobs, despite much greater job displacements in history, where that has always occurred?

Yes.

There's no new big source of un-automatable jobs that anyone can think of unless companies, nonprofits, governments, and/or the military-industrial complexes grow at an unprecedented pace.
