Francis Fukuyama and A Posthuman Future
Fukuyama later came to acknowledge that biotechnology will increasingly allow human beings to control their own evolution and become post-human.
Fukuyama is a vehement critic of transhumanism (H+), allegedly "The World’s Most Dangerous Idea", arguing that the transhumanist movement represents a threat to liberal democracy.
