One of my computer science professors when his laptop wasn't connecting to the projector: "I hate computers."

That's one of the ones who could program.

You enter the field with youthful exuberance, but long years fighting the war leaves you jaded.

Why do you think people become CS professors? One of the reasons is that they don't like working in the industry and maybe don't even know how to program.

That sounds like the correct response if he knows anything about the field: shitty peripherals are an unsolvable problem from top to bottom. The hardware sucks, the software sucks more, there's absolutely nothing you can do to fix it as an end user (unplug it and try again is where "debugging" ends), and the production chain will never improve along the quality axis because the margins are tiny and people are very price sensitive.
