Thanks @meno for your ever so gentle way to poke our brain-muscles into action. You're right; our brain is a muscle that has to be kept in shape in order to grow and function better. A big part of that is, as you say, to (be able to) escape your own echo-chamber. Especially nowadays it's becoming easier and harder at the same time to do so, because our echo-chambers are being automated in record speed, courtesy of Google, YouTube, FaceBook, InstaGram, Twitter... Well, mainly the first three. Search-algorithms are "assisting" us to find exactly what we like, they know what products we look for, what political viewpoints interest us most and also what interests our family and friends. This is how they make money; you are the product that's traded, your interests, your data. What was an echo-chamber rapidly becomes an echo-bubble...

Reaching out to other people has never been so easy, but it also seems people I meet online are increasingly harder to convince of a contrary opinions, and are always heavily invested in one of two opposing camps; there's almost no grey area, no common ground.

Especially when people are emotionally invested in the subject matter, the division between camps becomes sharper as well as the language used; I'm a big Star Wars fan, and you should see the rift that has fans divided since Disney took pver LucasFilms and specifically since The Last Jedi. Whole YouTube channels have been erected just to criticize that film and even to boycot future Star Wars films from Disney...

But I digress; just wanted to add the point about the search engines to your already wonderful post. And I wonder if you, or anyone else here has an opinion on the increasing divisiveness I seem to notice online; It could be my own info-bubble after all :-)

Thanks!
