@gianarb the problem is far less pronounced when you don't read (or write) posts condemning all of this mess. In practice you just use one or two tools that your team uses, and it doesn't take much of your time.
@thht if you want specifics, your point (2) is exactly why I don't use conda or mamba. See, I'm on Ubuntu, and I already have an excellent system package manager. I don't need a third party manager requiring me to give it sudo rights to mess with my system packages. It's going to break it.
But I do understand how it might be useful on Mac or Windows.
