All that happened was announcing said potential risks and then continuing to launch and push and release it anyways. Something that Anthropic continues to do under his leadership.

Google also analyzed for risks earlier in development of "Meena" and "Bard" and chose not to release, instead. And then got caught flatfooted when OpenAI did so anyways. (They also I think didn't really see a compelling business case for public propagation of it, either).

It starts to look very much like what is really happening with Anthropic is a lot of cynical attempts at regulatory capture. Make grand proclamations. Get your stuff out there first. Ask for regulation and then kick the ladder away from underneath you. But they did it clumsily and failed to grease the right palms.
