I would double your question except pip is a really bad example. There are many problems with it, pretty well known inside the python community and discussed many times, so I won't repeat all that can be found on the internet quite easily. In fact, package managers in python are pretty ugly story in general, every new generation of them being long and painful attempt to fix problems of the previous one, but unfortunately introducing the new ones.

npm would be a much better example, however not perfect as well. Actually, I would say all package managers we have are quite imperfect, but it's more of a existing implementations problem, not a package manager problem in general.

I mean, yeah, it would be nice if we all just started using guix or something, and wouldn't need language-specific package managers anymore, but it's not happening yet, right? And we have to live somehow until it does. And if I need to use language-specific package manager to be able to install a library that has a new version with crucial fixes on github since yesterday, and the version apt-get suggests is two years old — well, I'd better be using language-specific package manager. Still better than compiling it manually collecting dependencies all over the world over the next few hours.
