I don't know the problem space and I'm sure that the language-agnostic algorithmic improvements are massive. But to me, there's just something about rust that promotes fast code. It's easy to avoid copies and pointer-chasing, for example. In python, you never have any idea when you're copying, when you're chasing a pointer, when you're allocating, and so on. (Or maybe you do, but I certainly don't.) You're so far from hardware that you start thinking more abstractly and not worrying about performance. For some things, that's probably perfect. But for writing fast code, it's not the right mindset.
Uv is great but seems still everyone is cargo culting Rust. We still have Poetry and PDM.
The thing is that a lot of the bottlenecks in pip are entirely artificial, and a lot of the rest can't really be improved by rewriting in Rust per se, because they're already written in C (within the Python interpreter itself).
