It feels sort of weird to see such claims about a guy who was hacking on computer systems that were almost two decades ahead of everything else. (But that probably depends on what one sees as "technology". Shrinking transistor size is definitely technological progress, but I don't think that this alone has ever had a qualitative influence on the impact of computing systems - unlike their ubiquity, which, on the other hand, is not as much a technological advancement as it is a social one.)
