I've been a python dev for nearly 3 decades and feel that uv is removing a lot of the rough edges around dependency management. So maybe "problem" is the wrong word; I've been able to solve dependency management issues usually without too much trouble, I have also spent a significant amount of time dealing with them. For close to a decade I was managing other peoples Python environments on production systems, and that was a big mess, especially with trying to ensure that they stayed updated and secure.

If you don't see what the fuss is about, I'm happy for you. Sounds like you're living in a fairly isolated environment. But I can assure you that uv is worth a lot of fussing about, it's making a lot of our lives a lot easier.
