Strategy positions
Existential primacyendorses
Extinction/disempowerment risk overrides ordinary cost-benefitArgues alignment is unsolved, timelines are short, and most AI safety messaging understates the urgency; runs Doom Debates to stress-test the case in public.
If you actually take the technical alignment problem seriously, our position is dire. Doom Debates exists because the public conversation does not match the technical reality.
Pauseendorses
Halt frontier training until alignment catches upPublicly advocates for a pause or slowdown on frontier training.
My p(doom) is 50% and I think a pause is the only sensible policy.
