Open Philanthropy has kept the lights on at MIRI and CFAR since the beginning (also now Lightcone), as well as funding lots of offshoot “AI safety” entities like Redwood Research, the MIRI/CFAR summer AI camps at Berkeley and in Europe (that one itself almost certainly split off in response to the behaving-inappropriately-with-teenagers issue), academic AI groups founded or led by MIRI alums (Berkeley Existential Risk, others), I could go on. Ajeya Cotra (not sure if she’s still there) was active on LW for a while, maybe founded a magazine with Kelsey Piper? She I think was a program manager at Open Phil and oversaw a lot of the AI-safety funding work.
Ezra Klein appears to be an SSC/ACX reader from way back, and posted one of Scott’s pieces about race and policing in Vox more than 10 years ago (or maybe he was still at the Post?).
Dylan Whosit who is still at Vox has been a Scott superfan for forever (interviewed him around the time the Metalculus gathering - hosted at Lightcone campus, of course- was profiled in the NYT), Kelsey Piper got hired at Vox as a 23-24 year old on the basis of her rationalist Tumblr blogging, Vox even hired Scott to write an article once. Another major LWer/fanfic partner of Eliezer’s also got hired at Vox for a few years, Miranda Dixon-Luidenberg.
Klein is quite open about being an EA, asked Julia Wise to cover his podcast when he went out on paternity leave a few years ago, interviewed Kelsey and a number of SAC/ACX faves on his NYT podcast, and spent his first few years sanewashing AI safety issues in between his deeply uncritical conversations with conservatives and analyses of policy. I’m pretty sure he knows a lot of the rationalist bigwigs socially.
