> it's just another package manager among many

It's the python version of fink vs macports vs homebrew. Or apt vs deb. or pkgsrc vs ports.

But I don't think "its just another" gets the value proposition here. It's significantly simpler to deploy in practice for people like me, writing ad hoc scripts and running git downloaded scripts and codelets.

Yes, virtualenv and pip existed. No, they turned out to be a lot more fiddly to run in practice than UV.

That UV is rust is funny, but not in a terrible way. The llvm compiler toolchain is written in C but compiles other languages. Using one language to do things for another language isn't such a terrible outcome.

I hope UV supplants the others. Not to disrespect their authors, but UV is better for end users. If its worse for package maintainers I think the UV authors should be told.
