haha, well his methods, that live on after he's gone, are a big part of the reason people are now making GM at 12.
It's unclear whether these sort of players will do as good a job at handing down their knowledge though. Think about how little you remember, in much detail at least, about stuff before you were 12 - and now imagine you were already master strength by then, let alone a grandmaster. I'm a later starter and can still vividly remember when I barely knew how the pieces moved, and I think that gives me a huge edge over most players in terms of teaching.
