> I recently found a new a job hoping to gain some mentorship

I this is probably the real error. Lacking greater context, what made you expect that your boss at this new position would be able to mentor you?

Is he supposed to know how to parse a CSV? (Manually? Like, with awk or something?) Or is that why he hired a hacker/programmer like you?

I'm not saying your boss isn't incompetent. Maybe he is. But you shouldn't expect that your superior is always going to be more technically competent than you.
