There is a lot of "idolization" in the this industry. Those who have accomplished much are sought out for their opinions on all types of subjects, 1) because they are influential, and 2) there is some belief that the methods which led to their success in one field are applicable in the other fields they ruminate about.
I have no doubt Paul Graham has (or had) an anonymous account here. I'd love to see the responses to his comments there. I expect to see a bit of downvoting and people dismissing his (anonymous) ideas.
