This is related but in a kind of obscure way. I play low-level tennis, talking Div. 9 where there are 10 divisions in total. I play with and against a fair few juniors that are just cutting their teeth playing against seniors (learning how to 'play' a game of tennis having learned technique for years ad nauseum). I've lost to 12, 13, 14 year olds who are sensationally talented, but what's scary is that, if they're slumming in Div. 9 in their low-teens, they're pretty much out of the running for professional tennis already. This animation is likely an example of someone in that rarefied air combining natural talent, willingness to expend the effort on a single pursuit, and desire to see something through. This guy's a pro in the making, to continue to tennis analogy, at age 12 he'd have been cutting his teeth against div 3 seniors - In Div 9 I wouldn't even see this level of talent, even when it's up-and-coming (and maybe that's a good thing for my own motivation to continue playing and improving). Survivorship bias-ish?
