Clearly history is wrong. It would never be able to compile C in less than 18MB (1/2 of clang’s text size). Therefor Unix didn’t really happen. It’s all been a phone company conspiracy for world domination, like the NASA  not really putting a man on the moon. We were just *told* they had built a system in 1973 using a simple two pass compiler that would fit into about 28KW of memory. AT&T would have gotten away with it too, if it weren’t for their great  mistake—the 3B20. Results: no more “One system; it works."
