Open Philantrophy was founded by Holden Karnofsky who was Dario Armodei's roommate and is married to his sister Daniela Armodei. He now works for Anthropic, a company that is explicitly building AGI.
Working to build AI at the company that is most publicly discussing the risks posed by AI to humanity and most advocating for guardrails (while getting an immense amount of flack for implementing them independently) doesn't seem to support anything about what you, or rather the other person said, about sacrificing humanity for anything AI related.
Anthropic are explicitly building ASI, using recursive self improvement, with no knowledge of how to control it. They spend only a minimal fraction of their funds on safety work, none of which relates to controlling ASI.
I am open to being wrong about Anthropic, but it will be hard to convince me that a company developing ASI is prioritising safety. Do you really believe what they are doing is safe?
It's kind of like saying you can't kill everyone with weapons when you're looking at what you can buy at the local Walmart and not what's in the 1000 foot deep missile silo.
Also, it's kind of a once you build it, it's too late kind of issue. No model will be good enough, the problem is still in the future, we're all dead.
Instead, he is turbocharging development, otherwise said choosing to cause harm he warns about.
That is literaly example of causing harm now and in near future, not caring about people now, only about vision.
He works on the safety team and their responsible scaling policies. He literally may be working on slowing down AGI progress at Anthropic.
Hiring own husband to safety team while you raise money for (their words!) doom machine, while you do your utmost to scare people while you try to raise even more money from investors on doom ... does not show OP was not correct in their assessment.
