Targeting
Interesting that so many people want to discuss ad targeting but the elephant in the room, the very tech that is destroying our civilizations - SEARCH targeting - gets an open pass.
Thanks to Google Personalized Search, hundreds of millions of people are getting pulled into the rabbit hole of conspiracy theories, anti-vax, radicalized ideologies and violent behaviours. Just a few searches on any field brings you, and more importantly locks you, into an algorithmically-derived series of select answers...that the compose computer thinks you want to hear. Forget other views, other facts. Or any facts at all.
And it's destroying us. Reality is now what your search results can confirmation bias you to.
