Thing is world has learned from the collective past experiences. Esp. with stuff like nuclear technology and nuclear weapons. I hope everyone here remembers/knows shit like CTBT. At least some countries were smart enough to not fall for that in the past knowing what it would mean if they didn't have it and it shows.

Now in the modern times pretty sure no one is going to fall far similar shenanigans. Even though some countries might sign some notional MoUs or some sort of CAIBT (Comprehensive AI Ban Treaty. Translation: "Only US and US companies get to develop and decide AI on Gaad's planet"), they/we already know that an agreement means squat only if you are weak enough to let someone enforce that on you.
