I once knew a 2nd grade kid who was learning calculus and competing in AIME. An incredible outlier? Or is it possible for children to develop these skills through practice and early training? I wonder how many of our attitudes and beliefs towards early education are dictated by tradition (what we went through in our childhoods), vs. what is actually possible.

Think of the potential when someone learns to program at 6 years old, and keeps at it! I hate to use the word "disruption" but I really wonder if education could potentially be "disrupted."
