In all seriousness though, are we sure not one of those other 1,225 billionaires is "pursuing major advances in technology with a childlike wonder about the world’s potential"? When I hear about Elon Musk I tend to draw a different conclusion from the author of this piece: not that he is one of a kind, but that there are many more like him out there. I'm not sure which of us is right, quite possibly the author and not me - sometimes seeing X suggests 'generally ¬X' (http://www.overcomingbias.com/2013/03/when-seeing-x-suggests...).
