I think we all assume each individual company will need fewer developers to do the same work they're doing now. The question is do they have fewer devs or do more work. And if it is have fewer devs, will that open up the door for more small companies to be competitive as well, since they need fewer devs and have less competition for talent from people with deep pockets.

I find a lot of the AI discussion seems to land in the "lump of labor" fallacy camp though.
