I'm torn. The rise of python did massively increase the accessibility of programming, but it simultaneously tied much of the industry to one of the most poorly designed languages still in use. Simultaneously, the low barrier has created an ecosystem of poorly designed, yet de-facto packages. I'm not convinced it sped up long term progress, even if there's a lot more "code" out there.
I worry AI will do the same. Even less thoughtful programmers will beat the community to this or that package, quickly get taken up, leaving ever more tenacious code tumors.
