Why do you think Tallin holding ~1% of Anthropic would be a controlling interest that would allow him to force it to pause?
If he thinks the AI is dangerous or even omnicidal, that makes him an omnicide profiteer. That makes PauseAI funded by omnicide profiteering.
If he has no "controlling interest that would allow him to force it to pause", he can't even excuse the investment on the basis that it is helping to make the company more safe.
He is just profiting from the Anthropic's active development and sale of AI; if you think the companies should pause, it is clearly hypocritical to be living large at the expense of others.
Is there anything at all about this argument that is false, I think it is just straightforwardly true.
