So for an (employed) developer like me, who is dreading the next job search, what's a "hot" profession I could train myself on so my experience in the job market over the next 15 years could be like it was in the salad days of 1996-2022?

(I'm making a pass at "learning AI" but don't feel 100% certain that demand for that will be sustainable at a high level over the next decade ...)

Well, I'm currently having a hard time finding a good electrician, and the ones who I have employed in the past earn pretty generous hourly rates.

(I say this half-joking, but also I know a DBA who retrained as an electrician and was happier than ever. It's the fact he retired - early - which has put me in my current predicament.)
