I agree with that other reply.

Linus knew just enough to be dangerous.

My experience with most Windows users and their first encounter with using a Linux terminal is every single warning/error they see no matter how mundane is a big deal.

Things like the boot text or a random apt install on Linux will often display various warnings or even “errors” that are really of no concern but ime tend to freak out new users.

Linus is in that narrow band where he doesn’t really know shit but knows just enough to be falsely confident and ignore all the warnings/errors instead of just the irrelevant ones
