Another thing to appreciate while reading is that Risks started pre-Web, when the Internet was a much smaller place, so PGN's work on Risks was well-known, and presumably influenced the thinking of a lot of people.
As one example, I bumped into Risks in my teens (I think through Usenet comp.risks), at the internship start of my software engineering career. I now think back to things I said and did back then, and the formative influence of Risks is unmistakable.
Correctness? Safety? Security? Privacy? Societal implications? Responsibility?
The MBA-ification of the Internet came later, but before that, PGN helped educate and guide a generation of Internet-savvy people in the best direction.
