Thanks for this really well-written post, I particularly like how you clarified the different connotations of longtermism and also the summary table of cost-effectiveness.
I think one thing to note is that an X-risk event would not only wipe out humans, but also the billions of factory farmed animals. Taking into account animal suffering would dramatically worsen the cost-effectiveness of X-risk from a neartermist point of view. I think this implies longtermism is necessary to justify working on X-risk (at least until factory farming is phased out).
