It doesn't matter if it is GUI or terminal interface, software must be _humane_, forgive mistakes and provide a way out. As much as love Unix coreutils and have them in may fingertips, those are the least humane programs I have ever used.
Surprisingly, git seems quite humane, even when you screw things up it gives you a lot of safety mechanisms to recover.
You have to earn it. I admit that when I started using git sometimes I made a copy of the repo just in case I ended in a state that made it easier to nuke it and start again
There's also a psychological element to it. If you can verify for yourself that the repo can't possibly contain anything that would mess you up after an earlier mistake, it's much easier to do things than if you have to worry about using the wrong branch name when you don't know how to delete branches, for example.
I use a Mac for work, and one of the first things I did was to alias `rm` to the utility `trash`[0] -- instead of immediately marking the bytes as free like `rm` does, it'll move the file(s) to the system's trash can.
The problem is that filesystems don't get enough love. There are plenty of more fundamental problems that aren't going anywhere, so do not expect this to change.
