If this is really an existential threat, that's better than fifty of them.
Also, AI performance has proven to be a function of power and compute, and right now most of the compute lies between two companies rushing towards RSI not because they are afraid someone is going to do this before but because they are the ones who wants to build it.
I am not sure that it will.
But a balance duopoly tends to be better than a monopoly and if there are multiple poles then so much the better.
I'm past the point where I believe that any of these a-holes is in it 'for the good of humanity', their behavior so far can be extrapolated safely to what they will be like when they are in the control of what effectively would be the largest private arsenal ever created.
For a while I thought the AI doomers were off their meds and too paranoid but I'm coming around to the fact that they may have a point: we are rapidly approaching a point of no return, if we are not already past it and the people in charge are exactly the wrong people to be in charge at such a point in time.
Models don't go out of control, they generate totally harmless tokens. The people directing the models go out of control. The owners of the single powerful model are seriously tempted to go rouge and they're going to do it, sooner or later.
Two or more competing groups force the development of defensive capabilities which require strong models too. In addition, offensive capabilities in possession of different competing groups introduce the option of MAD (Mutually Assured Destruction) which is a form of defense that doesn't require defensive capabilities. Worked with nukes.
You cannot really hide an AI datacenter consuming GW of power for too long.
We've mostly been blindsided by covert nuclear programmes. As for weapons in space, they don't have any purpose. The moment they make sense we'll see weapons in space.
This does not exist.
So this is basically suggesting that USA and China should work together to ensure that they are the only ones allowed to develop and maintain capable AI. And between the two of them they can carve up and techno-colonize the rest of the world.

India
In 1998, India said it would only sign the treaty if the United States presented a schedule for eliminating its nuclear stockpile, a condition the United States rejected.[18]
Israel
In 2016, Israeli Prime Minister Benjamin Netanyahu said that its ratification was dependent upon "the regional context and the appropriate timing".[19]
United States
The United States has signed the CTBT, but not ratified it; there is ongoing debate whether to ratify the CTBT.

Nuclear powers also gave security guarantees that e.g. convinced Ukraine to give up its Soviet stockpile. We're almost certainly entering a new regime of proliferation due to the breakdown of that system.

"Iron Sky"
"Whoops Apocalypse"
"Wag The Dog"
and "Idiocracy"
You'd think we were amply warned.
