Except in technology where the gains come from my personal investment in skills. I'm spending hours every week keeping up with the field of software engineering. I've been investing in learning my craft since I was 14 or so.
I'd argue the same goes for many types of digital creators, artists, video editors, animators, and so forth.

Not really. That's essentially a weaver learning to use the new automated weaving machine. That is what you do to remain qualified for the job. Now, if you were a framework or key system creator, building the underlying platforms that get adopted throughout the industry, I would agree. But just learning to use the tooling the the industry creates isn't that different, other than the rate of change you have to keep up with.
