I seem to recall a post on his blog where he addressed this point. IIRC, his conclusion was that if it had not been him, then then the culture/movement/whatever would have eventually invented someone else like him. That is, someone would have eventually noticed the same things, come to the same or similar conclusions, recognized (or at least thought) they had the social skills/aptitude needed to successfully promote the ideas to the wider world, and gotten started. I can't disagree with that. The question to me is whether that would have happened around the same time, or if it would have taken several more years for the same things to click for someone else.
