Knowing VIM does not make one a better sys-admin. You can be an idiot, and still know how to drive Vi/Vim. There is FAR FAR FAR more to managing an OS and than that. If you think requiring VIM is enough to keep unknowledgeable people away from servers, you are probably the one who shouldn’t be managing servers.
There’s a sysadmin at my place who does exactly that. He’s kind of an idiot too.
It does not.
It entirely depends on the degree and career path you are after.
Oh crap, I missed that. I’m happy to delete (or you can delete) if you need. I won’t be offended
