I find reading this article a very uncomfortable experience. It's just assertion after assertion without evidence to back them up. Do people believe this guy because he's rich?
I can tell you why I love his essays: because of the way he argues. It is very transparent. I seldomly agree with his conclusion(s), but since he is so honest (he is not trying to deceive) in listing his arguments it is just a matter for me to find where he is wrong... or where I am wrong. I find this style so uncommon and stimulating that I hardly can stand the regular "opinion" held by most people. At least it is hard to be intrigued by arguments that doesn't even try to be precise.
When PG writes something I pay attention to the words, because I know they were chosen with some care. If I can force open a crack in his arguments I get wiser, and if I don't... the same thing happens.
I wish more people wrote like him, but preferably less about startups. They don't interest me as much as attempts at honest discourse.
