Searched around and found it. It was actually Ashton Kutcher's interview with Eric Schmidt.

Kutcher mentions the establishing shots, and I'd forgotten also points out the utility for relatively short stunt sequences.

> Why would you go out and shoot an establishing shot of a house in a television show when you could just create the establishing shot for $100? To go out and shoot it would cost you thousands of dollars.

> Action scenes of me jumping off of this building, you don’t have to have a stunt person go do it, you could just go do it [with AI].
