LWers don't just know it, they actually appreciate the insight [that life has a price], i.e. put it into practice and successfully avoid errors based on assuming something has infinite value. And, for that matter, I don't think that any of the newbies, except maybe the really "out-there ones", have made such an error.

Would this imply no Less Wrong readers believe in God?

Also, shedding the belief that life has infinite value is not a quick and simple process. It's more like the beginning of an ongoing process. It requires pricing many things we consider priceless, where plenty of cognitive biases will get in the way.

P.S. You're saying Clippy is "out there"? :)
