As you point out in your linked comment, the original essay captured the zeitgeist of the time. It also influenced and inspired many people. From that perspective, it's hard for me to agree that it was bad. However, I don't think the content was original at the time (perhaps that's what you mean by bad?) - in the sense that ESR wasn't out ahead of people blazing some new trail and it also didn't hold up very well factually.
It was certainly influential. It's just bad on its own merits.
Yeah, it's worth remembering that at the time a compiler cost $10k+, an OS $1000s/year - you couldn't work on OS or compiler work unless you worked for a big hardware company - a whole lot of interesting work was locked away from most programmers
