A few years ago I had the same concern, but it's been easy for a while now to create photorealistic fakes of anything you'd like, and in practice it doesn't seem to have been more convincing than any other form of lying.

We're splitting hairs here. Open up the ChatGPT window and have it do something nefarious without you touching the keyboard. Then these AG actions would make sense.
