Someone sent me this link (https://www.ted.com/talks/eli_pariser_beware_online_filter_bubbles.html).
It’s a talk about the growing prevalence of Internet content providers to present content that they presume you want to see. You go to Google News and the news you find is the kind of news Google thinks you like. You go to Facebook and the comments you see are the kind of comments Facebook believe you like. Comments from friends you were less likely to click on slowly vanish from sight… and you end up in a bubble of like-minded people, increasingly unaware of things that might challenge your thinking.
This is very bad. Indeed, I am beginning to wonder if perhaps the emergence of such information bubbles may be somewhat responsible for the increasing polarization in politics in many Western societies.
