Consider Dario was VP of AI research and oversaw alignment and safety at OpenAI. He left in 2020. In my opinion and from direct observation, it takes time to change policy at large well funded companies, so even after he left, his influence was still being felt.

I doubt Sam Altman is part of the effective altruism cult though - he’s more obviously looking for regulatory capture to give him moats.

The recent OpenAI post calls for mandatory safety certification of all frontier level models:

OpenAI is happy to sell their device to the gov’t to blow things up with, Anthropic tried to tell the gov’t to pound sand, no blowing things up for you.
