Or, could it be that it's the company as a whole, and not just specific developers, who bring us these amazing products? I mean, a bit like when you see an actor give a great performance in an amazing movie or TV show, and then you watch a new movie or TV show of that actor, and you realize they're just horrible.
Sometimes it's the environment and people around you that push you to do great things, and it might just be that without those things one doesn't amount to much.
