In case you don't know, Liv Boeree is a famous professional poker player and has recently been paying attention to existential risk and coordination problems. She's part of that vague celebrity circle around rationalist diaspora that includes Tim Urban or Aella.

Since you're on LW, this Ted Talk won't really teach you anything, but it might be interesting to know what kind of talks TedEd is hosting. Boeree has a podcast called "win win", and has made two videos on the race-to-the-bottoms in both the beauty world (not sure how to phrase that) and the news cycle. Some guests of hers have included Toby Ord and Simon Sinek.
