The other reactionary conservative concern is similar to the story in which the announcement comes over the aircraft PA system: "You are flying in the first fully automated commercial aircraft. It is programmed tyo deal with all contingencies. Rest assured that nothing can go wrong, go wrong, go wrong."

Deniers believe that they live aboard a fully self correcting planet which will correct itself before anything serious goes wrong. The system may correct itself but not necessarily before we are destroyed in the process.

I prefer soft landings myself.
