The Social Dilemma is a new Netflix documentary which discusses the effects of social media algorithms on mental health, human behaviour, and social interactions. In the film, Tristan Harris from the Centre for Humane Technology argues that these algorithms present an existential risk. Perhaps not one that "threatens the premature extinction of Earth-originating intelligent life" but one that threatens "the permanent and drastic destruction of its potential for desirable future development" (Bostrom, 2012).
Ivan Vendrov and Jeremy Nixon have written about Aligning Recommender Systems as Cause Area and Lê Nguyên Hoang has written about short-term AI alignment. However, I expect many EAs will find it valuable to discuss the arguments made in The Social Dilemma and I want to create a space for that to happen.
UPDATE (December 3, 2020)
Tristan Harris has been interviewed by Rob Wiblin on the 80,000 Hours podcast.
