[This is an entry to the 2019 Adversarial Collaboration Contest by Nick D and Rob S.]

I.

Nick Bostrom defines existential risks (or X-risks) as "[risks] where an adverse outcome would either annihilate Earth-originating intelligent life or permanently and drastically curtail its potential." Essentially this boils down to events where a bad outcome lies somewhere in the range of 'destruction of civilization' to 'extermination of life on Earth'. Given that this has not already happened to us, we are left in the position of making predictions with very little directly applicable historical data, and as such it is a struggle to generate and defend precise figures for probabilities and magnitudes of different outcomes in these scenarios. Bostrom's introduction to existential risk​ provides more insight into this problem than there is space for here.

There are two problems that arise with any discussion of X-risk mitigation. Is this worth doing? And how do you generate the political will necessary to handle the issue? Due to scope constraints this collaboration will not engage with either question, but will simply assume that the reader sees value in the continuation of the human species and civilization. The collaborators see X-risk mitigation as a "​Molochian​" problem, as we blindly stumble into these risks in the process of maturing our civilisation, or perhaps a twist on the tragedy of the commons. Everyone agrees that we should try to avoid extinction, but nobody wants to pay an outsized cost to prevent it. Coordination problems have been solved throughout history, and the collaborators assume that as the public becomes more educated on the subject, more pressure will be put on world governments to solve the issue.
