The bad versions should be developed, but they should not be marketed as a replacement for traditional education.

Volunteer trials, pilot programs, slow rollouts... there are plenty of ways to test a beta version without making the entire population guinea pigs for someone's shower thought. But such careful methods mean the conman might not get his big score.

Always watch out for the false sense of urgency. Remember when we had to invade Iraq immediately because weapons inspections weren't working fast enough?
