I was looking for this comment! One world government (could be highly federated, depending) is the only reasonable solution I see for world peace, climate change, global workers' rights, etc. It's an understandably unpopular idea, but the United States has arguably come pretty close (we have the standard world currency, naval patrols spanning nearly the entire globe, etc.). If we hadn't outsourced so much of our production to China starting a few decades ago, we would probably be within striking distance of true global hegemony at this point.

That being said, the field is much more competitive now. Whichever nation wins the weaponized AI race--which will presumably come with the benefit of advanced missile defense systems, cyberwarfare capabilities, and such--will be in a position to feasibly take over the world by the end of this century. Personally, I'm rooting for the United States/NATO/EU.

Politicians, DM me if you're looking for a maverick campaign advisor!

I don't know if you are serious but I suspect without a peaceful geopolitical resolution we may see WWIII arrive within a few years. And it will be dominated by superintelligent weapons control systems directing swarms of autonomous weapons.

And there is pressure to make them more and more autonomous because humans in the loop are too slow.

It doesn't seem like a safe direction.

I know that governments can be generally terrible and a world government is a lot of people's worst nightmare. But the alternative might be SkyNet. Or WWIII and then SkyNet.
