Although I like the attitude on some level and in this case he is obviously right, the problem with it is that our (and others I know) programmers feel like cowboys after reading HN posts like this. 'Ruby master bla says I don't need comments and documentation man!' 'Testing is sooo 00s; we use our brains!' 'Specs and standards are paper, read Torvalds; he uses that in his watercloset! Yeah he isn't talking about specs, but those are paper too!'.
