I find that P(doom) has nothing to do with how likely the world is going to end -- (obv no one can predict this with any remotely accurately take) 

I think it's a metric of how much existential angst that an AI Researcher is feeling on that particular day

creating and destroying; built flying cars & autonomous vehicles, now building /faust, more here: /july, web: july.rocks

Generally agree, but I think "nothing" is overstating. 

You can constrain the probabilities within a range of {certain doom | likely doom | unlikely doom | no way doom } and then existential angst moves the numbers within the range.
