I am reminded of how much more difficult it would be to drive a car, if you had no Reverse gear. Our society, generally, has only every once in a great while successfully reversed on a technology. This means that we have to either ban it proactively, which requires us to be able to predict its consequences, or else adopt it and hope for the best. The Amish subculture seems to have a functional reverse gear, allowing them to try out a technology and then decide not to allow it after all. It would be a good feature to have, for our society more generally.
