Got it. According to BLS, there are 29,530 radiologists out of 20,736,000 total employed in healthcare in the US.

My take on the bigger point is, I wouldn't be so sure about the economy-wide apocalypse. I agree with what he said about the outsourcing scare of 2000's, and if pure cost+customization of education, for example, were an issue, you could conceivably hire a very good personal tutor (professor even) from a low-COL English speaking country, even like 15 years ago, or build yourself your own full custom curriculum for free from MIT videos and plentiful other information that has been around forever, mostly for free. Yet, colleges haven't been abandoned, people are taking on more and more debt every year just to be a part of that system. This is probably not technological in nature. Same for healthcare, there are so much money (and technology) getting poured into that but the system keeps getting more expensive and not too much more efficient, will probably start regressing at some point.
My personal point of curiosity was that autonomous driving, which 10 years ago was promised to have fully arrived 5 years ago, among other things would have turned 2,000,000 not-very-retrainable-in-such-numbers truck drivers in the US into basically near-homeless people. Well, it hasn't really happened:

We've been, too, promised that AI will revolutionize healthcare, e.g. that Watson will replace your doctor (at least, according to the IBM and friends' pitches). Watson turned out to be less than a rounding error in the healthcare equation (i think they got rid of parts of it by now).
The point being, to me it's not very clear cut, and some of what MA pointed out seems really to be caused not by inferior pre-ChatGPT technology but for more societal/economical reasons and incentives (perverse or not).
