Not to be cynical about it BUT a few safety papers a year with proper support is totally within the capabilities of a single PhD student and it costs about 100-150k to fund them through a university. Not saying that’s what Anthropocene does, I’m just saying chump change for those companies.
You are very off (unfortunately) about how little PhD students are being paid
Sometimes I think people misunderstand how hard of problem AI safety actually is. It's politics and mathematics wrapped up in a black box of interactions we barely understand.
More so we train them on human behavior and humans have a lot of rather unstable behaviors.
