Telling most people in the AI community about AI risks is similar to telling neuroscientists that their work might lead to the creation of a society of uploads which will copy themselves millions of times and pose a risk due to the possibility of a value drift. What reaction do you anticipate?

One neuroscientist thought about it for a while, then said "yes, you're probably right". Then he co-authored with me a paper touching upon that topic. :-)

(Okay, probably not a very typical case.)
