I was about to jump on an airplane, and didn't really have time for a nuanced response. The OP comment is, likely, from someone who has no idea what hacker culture was like in the 1970s and early 1980s, so I can see how he doesn't find it very relevant to his life today.
And he's absolutely right that it was angsty venting (I was 19, so I'll even allow adolescent). That doesn't mean that it didn't resonate with multiple generations of hackers in the 30 years since.
