He's now on X bashing Anthropic for taking this same stance. I know this would be expected of him, but many other Google AI researchers signed this as well as Google Deep Mind the organization. We really need to push to keep humans in the kill decision loop. Google, OpenAI, and X-AI are are all just agreeing with the Pentagon.
