I reckon it's quite difficult. A lot of the old stuff doesn't really have any money in it, which means no professionalized training, meaning no university textbooks. My advice - try to break the law on the computer. Not anything super illegal, but try to download a movie or three, see what sort of technology you have to use to get it working good. If you're just interested in self-hosting, look into sysadmin stuff. I don't think you need programming skills, but maybe some shell scripting etc. Luke Smith on YouTube has a bunch of good videos about that, setting up a website and so on.
