The speaker considers it plausible that a future society could use an AI that knows what is happening everywhere but keeps that information private and does not interfere, as directed by liberal values.

“I think it is plausible to imagine a future society that works the same way.”

“This may be in some sense a surveillance state in the sense that there is some AI that knows what's going on everywhere,”

“but that AI then keeps it private and doesn't interfere because that's what we've told it to do using our liberal values.”
