"Charlatan: a person falsely claiming to have a special knowledge or skill" - I dunno, his achievements tells me he's the real deal, and if he's not, he's an AMAZING charlatan.
I find it hard to take something like this seriously when there are so few people on this planet who have done even a fraction as much as he has to advance our tech and our knowledge. So what if he's extremely privileged? He's used his priviledge for the benefit of so many, that's really not a crime, whatever his intentions may be.
Perhaps you should put some time into an investigation as to what you would have done differently / been capable of doing given his starting situation before you start calling him out for being so far beneath you and your ideals.
