This is an interesting subject and conversation, but it's moot having it in these culture-centric forums. I wonder if there are Russians discussing plausible scenarios in Vkontakte groups, or Chinese doing the same in whatever Alibaba group sites they use.
The problem is that we are all skewed by our media, our ideas and our culture. These type of discussions need the highest kind of political interactions.
It's fascinating, specially for someone who lives in a "third world" country, non-aligned to any of these 3 superpowers. Whatever transpires, we are at tge mercy of these (and no, US hasn't treated us "better").
My opinion is that there's no turning back on AGI development. I dont think current governments are capable of getting into an agreement of that size. Specially given the Isolationist stage in the cycle we live in. (In contrast with for example the CFC and Ozone layer issue we had in the 1990s, when the planet was in a globalist kind of stage)
