Techno-feudalism and the rise of AGI: A future without economic rights?

Will there be only one AGI? Or will there be several, all in competition with each other?

If they become self improving, the first one would outpace all the other AI labs and capture all the economical value.

That depends on how optimized the AGI is for economic growth rate. Too poorly optimized and a more highly optimized fast-follower could eclipse it.

At some point, there will be an AGI with a head start that is also sufficiently close to optimal that no one else can realistically overtake its ability to simultaneously grow and suppress competitors. Many organisms in the biological world adopt the same strategy.

There are multiple economic enclaves, even ignoring the explicit borders of nations. China, east asia, Europe, Russia would all operate in their own economies as well as globally.

I also forsee the splitting off of nation internet networks eventually impacting what software you can and cannot use. It's already true, it'll get worse in order to self-protect their economies and internal advantages.
