And i think, a lot of that has to do with your culture.. people should take this kind of thing more into consideration, try to understand what the "secret ingredient", and try to replicate the things that work somewhere else.
I mean if a world-renowned workaholic genius can't automatically generate a fair amount of wealth from decades of creating some of the most used and influential software in the world, what does that imply for the rest of us?
I also don't see him as a world-renowned genius (as you put it), because he isn't one and from what I've understood from watching his talks & reading the mailing list he himself does not want to be refered to as one either. I think that people should keep that in mind when they read articles about Linus, because most articles tries to portray him as some kind of higher form of being among the likes of Steve Jobs & Gabe Newell, which I believe is not the way he'd like to be perceived when you read a sentence he spoke.
Tech-world renowned I should've said. And he may not be a self-proclaimed genius but he has a level of talent which is surely rare, at least.
I'm sure Linus is living a very comfy, happy life - even though his Net Worth isn't greater than the guy who made Instagram.
