The the most in the future: AI is greatly more intelligent than humans. We delegate all powers to it as it's just stupid to decide anything ourselves. AI decides it doesn't need us, or it just ◊◊◊◊◊ up. Yes, even superintelligence can ◊◊◊◊ up. Parents are superintelligent compared to their children. It's not that they can't ◊◊◊◊ up. It's just the children can't see or even understand the nature of the ◊◊◊◊ up.
Closer future: AI is somewhat more intelligent, but vastly faster in decision making. We delegate some powers to it, most likely in crisis, like climate change or war. AI is still very dependent on us, so it won't rationally conclude it doesn't need us. But it can still ◊◊◊◊ up.
Very near future, possibly now: AI is about as intelligent as top 1% of humans. It also has vast knowledge above any human. Bad actors use it to design a weapon of mass destruction, like a virus. Fully synthesizing a virus from scratch is increasingly accessible, and perfectly doable if it's state level bad actors. AI decides nothing, but plays key role.
