This is both very entertaining and very informative. It's also very scary if you are one who is concerned with maintaining freedom. The idea of a future, where integrated sensors that give us "points" for activities is very frightening. The manipulation of human behavior through the rewarding of "points" isn't something that needs to be understood. I think this guy has a handle on it and, while he thinks it could be used for good, that is a small, almost microscopic chance because it's too easy to use for evil.
