Is there anyway we could contact Musk? I believe there is a nonzero chance that he could have an idea about what to do that has not yet been considered on LW, if for no other reason than he is a very intelligent outsider who seems to reason about everything from first principles.
I don't think that LW is a good vehicle for this. Within MIRI's interview experts series they could ask Musk. People at the head of MIRI or FHI might also reach out directly to Musk.
"I'm increasingly inclined to thing there should be some regulatory oversight, maybe at the national and international level just to make sure that we don't do something very foolish."
