Three of my forty coworkers actually understand the command-line on a level nearly on par with me, and I'm not an expert (locally, yes; globally, hardly). It's been frustrating me since my first real job in industry and others in government. I think I got spoiled in college by being surrounded by (mostly) curious tinkerers who had no problem delving into the multitude of tools that were available and exploring them. Post-school, people seem to lose that curiosity, if they ever possessed it, as a group.
I've been in job situations where just picking up a handful of hotkeys for a program is seen as Deep Wizardry. Most people just never learn how to do things like that.
It sounds like you took the wrong job. I was surrounded by curious tinkerers in school, and I'm very happy to say that at my first two jobs I have been surrounded by curious tinkerers.
Possibly, but doubtful. I suppose really it's the unwillingness to learn (by otherwise educated and intelligent people, so they have or at least had the capacity for learning at one point). This is just a glaring example in the programming field. We literally program computers to do whatever we want (modulo performance or physical limitations), why would our tools be any different?
