Well there probably would be more those kind of genius-autist-savants if children were allowed and encouraged to pursue their interest. Instead what usually happens when and if a child becomes obsessed with some topic is that instead of allowing child to pursue what he is passionate about by guiding a child towards a more constructive path(if necessary), he gets penalized for it. Repeatedly and as often as it takes for the child to stop dreaming. And that is such an incredibly stupid waste of human resources.
