But if lots of people use it wrong and break it then maybe it’s too obtuse. I broke one of my applications by upgrading packages. The solution? Install the package again, I thought the package manager would take care of stuff like that but if it’s meant to be me then I think it’s a bad system.

I broke my install by updating it, I get that if you perfectly understand what’s going on then it has no bugs but that’s really not my experience. A lot of the time something will break and it’s easy to say “I should’ve known it was this so it’s my fault” but really if you didn’t expect it to work a certain way and it breaks it’s not a super stable system.
