10% chance of extinction indeed is ridiculous
here are my priors for various doom scenarios in next 10 years
p(extinction) = 0.0001
p(terminator war) = 0.0002
p(super covid) = 0.001
p(cyber attack that leads to >1k deaths) = .5
p(autonomous weapons used in war) = .9
p(>25% of white collar work disappears) = .9
p(mass fraud) = .99
