>The whole world, sans programmers, keeps moaning on complexity of computers, and Unix, and how hard it is to learn all those arcane commands and abstractions and why things can't be just plain and simple. I'll skip rants about how it's related to file abstractions

It says "no one, in the unix world". People outside of the unix world are not in the unix world. The point is, unix became very popular despite being bad (or perhaps because of being bad). Even within unix, the worse a system is, the more popular it is in general (see a typical linux distro full of randomly tossed together junk).
