On the flip side, we've had many thousands of years of adversarial training, so it's not as if protections don't exist—at least for a very classical modes of attack.
Humans don't have those protections. Although, ego deludes oneself to believe they do. Ask anyone if they are susceptible to advertising. Maybe 1 in 5 have the humility and awareness to state the truth.
It's not hackable so much as it lacks resistance to environmental noise.
Even when we can use that awareness to notice the times that we're being manipulated and try to remind ourselves to reject the idea that was forced into our brain surveillance capitalism means that advertisers can use the data they have to hit us when they know we're most susceptible and our defenses will be less effective. They can engineer our experiences and environments to make us more susceptible and our defenses are less effective. They're spending massive amounts of time and money year after year on refining their techniques to be more and more effective in general, and more effective against you individually. I wouldn't put much faith in our ability to immunize ourselves against advertising.
I do not trust my in-built protections, so I’d rather not be exposed in the first place.
