Jeez. I thought human extinction was a given. I already saw 2001: A Space Odyssey. Here is improved version:

Why would human extinction be a greater risk than human existence becomes unbearable and also we can't end it? I don't want to live in a world with no music or inside jokes or privacy.

Let the record show that there is an ambiguity in the question. "Greatest" can be interpreted to mean either "most likely" or "most impactful".

@asmith I agree. I'm not expecting traders to calculate an expected value based on each risk though. That would be very silly considering the broad ranges involved, plus what if someone thinks several of the possibilities existential threats. I'm inclined to think resolving this ambiguity would be a distraction but I'm open to persuasion.
