This has been used, repeatedly, through history.
Now, where AI could be applied would be in having a tailored, sculpted false narrative for each and every subject, which could be used for mass sentiment manipulation - profile each target, determine the ideal narrative to achieve the desired emotional and behavioural outcome, implant, rinse and repeat.
Could be used for nefarious purposes, could be used for benign purposes - although it’s hard to see anything that involves the mass brainwashing of a population as benign. Perhaps it would be useful for deprogramming - undoing the effects of the currently prevalent methods where desirable, such as indoctrinated cult members, dictator worshippers, and religious zealots - but right there in my postulating you see scope creep, and that’s why it’s almost inevitable this will end up being applied for marketing and programming purposes.
Remember when you first fell in love with Morbo brand human kibble? We do.
I mean advertisements already are basically brainwashing right? quirky jingles or catch phrases associated with some food or product, that stick in your head.
I am a hypothetical gun shop owner and want to increase sales, so I put up ads that talk about the need to defend against high crime rates onto any search that might be related to the local area, anything about security, anything for new renters and owners. Without telling people that the area has a high crime rate, people will start to believe that it does, and that they need to protect themselves.
So: Why google Paris? Why even Paris as an example? Hell - why Paris, period?
Examine your answer carefully, and you’ll see the non-sequiturs in our reality that we usually happily ignore.
Many people imagine companies indoctrinating the population but we are brushed off with "the first amendment only applies to the government" and nonsense about how companies and platforms don't have to uphold free speech because they're not the government, they don't owe you anything, and if you don't like it find another company to do business with.
It's definitely disturbing how people will give corporations leeway to inflict harm upon society because they're not the government.
My point with this comment is that companies already use censorship to create a false narrative of the public opinion so it shouldn't surprise us that they'll use AI on top of that to achieve the same goals. They won't even have to censor people if they can create an infinite on-demand stream of content that supports the narrative they want to push.
