The biggest barrier for people with knowledge, understanding, expertise, and the willingness to work hard was certainly time. But there were a lot of people with plenty of time that never got anything done.

In the beforetimes there were a lot of would-be founders running around looking for people who actually knew things and could do things (that is, technical cofounders). Will some of those people use Claude Code to make successful products on their own? A few, I'm sure. But I expect a lot of them will stay ignorant fools who have prompted their way to a pile of garbage.

I can be confident of that because there were plenty of founders with FFF money who could suddenly hire "capable coworkers" that produced garbage. "AI" is certainly removing barriers. But as I deal with a big increase in polished but idiotic email and PRs, I have to think that barriers were helpful both to the world at large (by keeping fools at bay) and to the promising but incompetent (by giving them a chance to build character and wisdom).
