> The synthesized clips line up with what each region is known to care about, faces for FFA, places for PPA, bodies for EBA, motion for MT, patterns for V1 / V3A, and lively social scenes for pSTS / aSTS

(STS seems to be https://en.wikipedia.org/wiki/Superior_temporal_sulcus in the temporal lobe, so I guess it's the "I sense a presence" region.)

Explain the potential to exploit strong stimulation of specific visual regions for evil. "Oh, I very much detect a face/place/body/motion/pattern/human", says the subject. What are you going to do with that, startle them?

Apply the same technology several layers deeper. Stimulate the novelty or sexual attraction or general reward neurons. Stimulate the thirst center in a Pepsi ad.

Do you know that strongly triggering these regions at the same time/repeatedly/in various patterns doesn't have any effect on your mood, wants, needs and so on due to experience in the field? Or why are you just discounting the idea?

IMO it's terrifying to imagine that adtech companies could plug this stuff into their optimizers and just run an experiment on broad swaths of the population to figure out if there's any effects.
