No, if OpenAI is reaching singularity, so are Google, Meta, and Baidu etc. so proper course of action would be to loop in NSA/White House. You'll loop in Google, Meta, MSFT and will start mitigation steps. Slowing down OpenAI will hurt the company if assumption is wrong and won't help if it is true.
I believe this is more a fight of ego and power than principles and direction.
Personally as I watched the nukes be lobbed I'd rather not be the person who helped lob them. And hope to god others look at the same problem (a misaligned AI that is making insane decisions) with the exact same lens. It seems to have worked for nuclear weapons since WW2, one can that we learned a lesson there as a species.
The Russian Stanislav Petrov who saved the world comes to mind."Well the Americans have done it anyways" was the motivation and he didn't launch. The cost of error was simply too great.
Eh? That would be an awful idea. They have no expertise on this and government institutions like thus are misaligned with the rest of humanity by design. E.g. NSA recruits patriots and has many systems, procedures and cultural aspects in place to ensure it keeps up its mission of spying on everyone.
