the need for the specialized skills of an expert photographer are much less than in, say, the 1930sWithout even looking it up, I expect that this is patently untrue. I bet way more people make a living as photographers today than in the 1930s.
EDIT: yep, about 4x as many today, and slightly more per capita even.
Not saying your overall point is off, but the fact that you picked a bad example is illustrative of a broader point: it’s very difficult to tell in advance how technology will impact employment.
EDIT: can’t reply so I’ll just add this here:
As I understood it, your entire point was that people don’t have as much need for photographers, dressmakers, and cabinetmakers today, because technology has given us low-skill or no-skill options that are good enough. Is that a fair characterization of your argument?
This is definitely true for some categories (agriculture, or elevator operators), but again, there are more professional photographers working today than in the 1930s. It wouldn’t surprise me if there are more seamstresses / tailors / etc too, more professional carpenters, etc.
Some of this is basic Jevon’s paradox in action, and some of it is just that median American is much wealthier (in real terms) than a century ago, so even though we can buy lots of “good enough”, there’s still a larger market for high-end skilled artisan labor than a century ago.
