  1. The 4 stages of cognitive development of Piaget have not changed, the time it takes for a human brain to fully develop has not changed, the distribution of human characteristics in any given population has not changed, and has not, for perhaps 60,000 years. It's one thing to pull out of a bundle of facts the pieces which no longer function, or found to be false, but to throw the entire bundle into the flames and start over, is ludicrous, has never worked, and in fact, creates the very dystopia you are fearful of. Stop it.
