The best arguments for Google's algorithms making people crazy for lay people would be Aaron Swartz like individuals who just go unknown.
I can think of atleast 4 individuals new to me the last 6mo ive discovered who used to cover court cases, ran NGOs, or worked as journalists that have been seemingly swept up in what looks like delusions.
Lots of typos, egegious oversights, etc#. Its hard to personify these individuals as theyre hard to reach and anyone w ptsd or whom knows people w ptsd know how hard it is to provide support to someone locked in a fight-or-flight reflex. After a terror/fear/paranoia becomes familiar anything else feels foreign. Human connection becomes scary.
Read up on bateson-esque schizomogenisis and reflect on the CIAs relation with the "unabomber".
The fact that it has been reported by groups like Amnesty International that Facebook helped to enable the ethnic violence in Myanmar makes arguing this sort of point much easier. People want to treat complaints about attention economy companies like they are coming from whiners who just don’t like ad profiles. It is useful to have specific information to remind people of the actual stakes of uncontrolled, personalized propaganda and social manipulation that these companies can enable.
So if you have one for Google I’d definitely be interested in adding it to my collection. (I’ll admit some bias, I think they are a little better than Facebook, but that bar is so low, let’s be careful not to trip over it).
