I’ve been feeling pretty shaken since the METR report about the Hugging Face incident came out last week. Over the weekend, I wrote up some thoughts on how lonely the AI situation sometimes feels to me.

Applications to SPAR Fall 2026 are closing tomorrow Aug 18 EOD Anywhere on Earth. SPAR is the ecosystem's biggest AI safety research program, and it's part-time remote.
We still have many strong projects across AI safety, AI policy, and biosecurity with very few applications[1], so please consider applying! This round, we also have 18 non-research/generalist projects that people can apply to, and we have much more mentee capacity than previous rounds; we expect to accept around 500 people into the program.
If you have friends who have thought about going into AI safety, spread the word!
To be specific, as of 2:25 PM PT, we had around 67 projects with fewer than 20 applications total!
