Thanks for the recommendation, it looks interesting but sounds like it pretty much agrees with what I’m saying.

Algorithms do what they are designed to do, but nobody knows exactly how society will be impacted by that. On the surface, delivering people with a feed of information that matches their interests seems like a good idea. The problem is that people are often interested in divisive topics and reinforcing their existing views, so anything that makes it easier for people to find these topics has a divisive and radicalising effect.
