If all AIs are scheming, they can take over together. If a world with a powerful AI that is actually on humanity’s side is assumed instead, then at some level of power of friendly AI you probably can run unaligned AI and it will not be able to do much harm. But just assuming there being many AIs doesn’t solve scheming by itself—if training actually works as bad as predicted, then no AI of many would be aligned enough.
I’m talking about the how of takeover. Could any AI, even one of many, take over successfully in its first attempt?

All AI’s scheming co-operatively is less likely than on scheming.
