You’re right, mostly.
The trouble here is the scale.
This is most definitely the first time this has happened at such a scale.
I think the scale is what most do not understand or are afraid to admit.
I retired from a job that could theoretically be done by AI.
The main problem with doing that is that it would take many thousands of hours of programming time—with the assistance of current subject matter experts.
That may happen eventually—but the job is very specialized and done by very few people so it would be a low priority to spend all that effort with programmers.
AI will go for the low hanging fruit first.
