"Extropianism, also referred to as the philosophy of extropy, is an "evolving framework of values and standards for continuously improving the human condition"
Notable extropians:
Julian Assange
Nick Bostrom
Wei Dai
Eric Drexler
Hal Finney
Robin Hanson
Todd Huffman
Marvin Minsky
Ray Kurzweil
Nick Szabo
Eliezer Yudkowsky
My suspicion is this says more about who wrote this list than about the extropian community.
E.g. Bryan Johnson is missing from this list. Making a list about notable extropians but excluding Bryan Johnson is like making a list about notable physicists but excluding Newton and Einstein.
