But two things to learn at HN if you don't want downvotes: (1) Never speak ill of wealthy people, and (2) Do not even imply driverless cars are anything less than the glorious solution to every problem in the western world... that and bike lanes.
All that said, one must learn to distinguish between a bad company and a good person (or a person playing different roles). I am a big fan of Gates in his post retirement avatar. He comes across as very earnest and well meaning person. Apart from his role as heading his charity foundation, he has good literary tastes ( picked up 'Guns, Germs and Steel' only based on his reco, about which I posted 9 days ago as well[1]), and a way of finding hidden gems (e.g. he was instrumental in making Khan Academy popular in its earlier years, when one fine day he suddenly mentioned it in one of his talks that he uses that to teach his children).
So its not at all that hacking community are fan boys of all billionaires. Remember he was earlier hated by many. And now loved by many. You should try to be fair in your judgement, that's all.
