I'll bet the author of this article has never been around MG/PG kids who have been radically accelerated.

The subtle assumption is that all kids are the same, in skill level and motivation, and that is not true.

A lot of red-shirting occurs around here. Mostly for sports reasons. And by 6/7 years of age, kids are already segregated onto "premier" teams vs regular teams. You've got kids who can throw balls 50 yards and can run 6.0 40s. Imagine suggesting they stick to learning how to throw and run.

If we put the same level of thought into academics that we do sports, things would be different.
