CEO Dario Amodei published the warning in the aftermath of the viral resignation of whistleblower Jacob Coxon, who said AI was posing an existential threat to humanity.

Amodei urged rivals to invite embedded external auditors into their offices and coordinate a slowdown in development of AI that would allow regulators to catch up.

Amodei’s essay comes on the heels of an Anthropic researcher’s resignation over concerns that the firm and its competitors are not acting responsibly with AI development.
