You don’t have to learn recipes to be able to craft them. Just having a book with one in vicinity already adds entries into the craft menu. As much as I know you can use book recipes even without being able to read.
All skills can be learned without books and even though it would take a shitton of time, it’s still possible.
Computers are rather meaningless except for fluff and lore. Most of them serve as door openers and you can do it the straight way. The only things that can be done only using computers [so that you WILL miss them] that I know of are:
Launching and disarming nuclear missiles, activating amigara horrors, all operations with resonance cascades and decypher from labs, radio towers.
Not really many but still sucks a bit. For everything else you use acetylene torches, jackhammers, sonic resonators, explosives and shit.
