"The Sol reflected Lee Felsenstein’s apocalyptic fears, shaped by post-holocaust science fiction, that the industrial infrastructure might be snatched away at any time, and people should be able to scrounge parts to keep his machine going in the rubble of this devastated society; ideally, the machine’s design would be clear enough to allow users to figure out where to put those parts. “I’ve got to design so you can put it together out of garbage cans,” Felsenstein once said. “In part because that’s what I started from, but mostly because I don’t trust the industrial structure they might decide to suppress us weirdos and try to deny us the parts we need.”"
From Hackers: Heroes of the Computer Revolution, Steven Levy, 1984.
For some reason, in the many years since I read the book, the bit about garbage cans has always stayed with me.
