"* From this perspective, I suppose Unix got composability right but its approachability to the average person is nearly zero.*" I strongly agree with the first part of the sentence, but I disagree with the second. Considering the users that the Unix developers had in mind at the time---the late 1970s to late 1980s, say---its approachability was significantly better than the alternatives. (DCL, anyone?) It wasn't until Unix expanded outside that niche that people began having bad reactions to it. :-)
