I doubt either will happen. Climate change was dangerous enough that it required everyone’s cooperation to stop it in the 1980s, and here we are still in denial. My only hope for the future is that multiple AGIs are just as dysfunctional as humans are.
Evil AI Overlord: "Silly humans! The only way to defeat me is to stop being bigoted and to transition to clean energy!"

If they are just as dysfunctional, they're going to start fighting wars against each other eventually, and will need cannon fodder for that just as human rulers do, no? ~
