I find the vast majority of complaints come from people who refuse to put any time into learning a mildly complex tool, and thus I have no sympathy for them. The documentation is right there in your terminal, in addition to many websites, videos, and books.

The one and only time I messed up a repo beyond repair was when I deleted some git pack files while trying to delete some binary files from the git history. This is known as user error.

In my day to day use I find that I rarely have to venture beyond rebase, bisect, reflog, cherry-pick, and the standard commands.
