I have no aversion to Rust (I've read some of it, and while foreign, it comes across as much more pleasant than C or C++), but the way it's promoted often is grating. I'm getting really tired in particular of how the speed of Rust is universally described as "blazing", and how "written in Rust" has a sparkle emoji as mandatory punctuation. But maybe that's just because I'm, well, older than Python itself.
I don't really care that the reference implementation isn't self-hosting (although it's nice that PyPy exists). Using non-Python for support (other than IDEs - I don't care about those and don't see a need to make more of them at all) is a bit grating in that it suggests a lack of confidence in the language.
But much more importantly, when people praise uv, they seem to attribute everything they like about it to either a) the fact that it's written in Rust or b) the fact that it's not written in Python, and in a lot of cases it just doesn't stand up to scrutiny.
uv in particular is just being compared to a low bar. Consider: `pip install` without specifying a package to install (which will just report an error that you need to specify a package) on my machine takes almost half a second to complete. (And an additional .2 seconds with `--python`.) In the process, it imports more than 500 modules. Seriously. (On Linux you can test it yourself by hacking the wrapper script. You'll have to split the main() call onto a separate line to check in between that and sys.exit().)
