(Introductions by Professor Rob Reich, President Marc Tessier-Lavigne, and grad student Margaret Guo end at 13:52.) Twin revolutions at the start of the 21st century are shaking up the very idea of what it means to be human. Computer vision and image recognition are at the heart of the AI revolution. And CRISPR is a powerful new technique for genetic editing that allows humans to intervene in evolution. Jennifer Doudna and Fei-Fei Li, pioneering scientists in the fields of gene editing and artificial intelligence, respectively, discuss the ethics of scientific discovery. Russ Altman moderated the conversation.
