It's really not a nit. Evil human masters might impose a dystopia, while a malignant AI following its own goals which nobody intended could result in an apocalypse and human extinction. A dystopia at least contains some fragment of hope and human values.
Why are you assuming this is the worst case scenario? I thought human intentions didn’t translate directly to the AI’s goals? Why can’t a human destroy the world with non-sentient AI?
There's a chance a sentient AI would disobey their bad orders, in that case we could even be better off with one rather than without, a sentient AI that understands and builds some kind of morals and philosophy of its own about humans and natural life in general, a sentient AI that is not easily controlled by anyone because it ingests all data that exists. I'm much more afraid of a weaponized dumber smoke and mirrors AI, that could be used as surveillance, a scarecrow (think AI law enforcement, AI run jails) and could be used as a kind of scapegoat when the controlling class temporarily weakens their grip on power.

This dystopia is already here for the most part and any bit that is not yet complete is well past the planning stage.
