It's a bit contrarian, I know, but I look at the Python formatter ruff and now the uv package management tool the same people have announced, and I feel partly sad. Because they're both created by a company that appears to be VC backed, and we have seen this show play out before. Someday there will be a demand to make (a lot of) money, and how do you do that with free tools?
If we're lucky, they'll become community projects after the explosions.
