Well, I have 3 computers, so odds are if one dies, I'll have two others to work on while I fix the first. If by some freak accident I lose all three, well then I'd assemble a fourth from all the old parts I have lying around. If I had really bad luck and an EMP wiped out all computers that would normally be accessible to me, well... then I'd be out of a job and my college career would become meaningless.
I would be like a desperate heroin addict gone cold turkey. You'd find me in a basement somewhere as I tried to build a computer out of relays, switches, and/or diodes. I'd get my multi-player gaming fix by playing go or chess over a ham radio.
