I would consider myself a fairly technologically competent person, but one thing that's completely baffling to me is audio. I have no idea how to set up anything more complicated than stereo. It seems like TV these days assumes you have 5.1 or whatever (at least, that's my assumption for why everything is mixed so badly) but I would have no idea where to even start if I wanted to do that. But I have bad hearing anyway, so I guess it doesn't matter.
