Suppose misaligned AIs take over. What fraction of people will die? I'll discuss my thoughts on this question and my basic framework for thinking about it. These are some pretty low-effort notes, the topic is very speculative, and I don't get into all the specifics, so be warned.
I don't think moderate disagreements here are very action-guiding or cruxy on typical worldviews: it probably shouldn't alter your actions much if you end up thinking 25% of people die in expectation from misaligned AI takeover rather than 90% or end up thinking that misaligned AI takeover causing literal human extinction is 10% likely rather than 90% likely (or vice versa). (And the possibility that we're in a simulation poses a huge complication that I won't elaborate on here.)
