Ask HN: Do you think social media and AI help making the world more divided

Just finished watching Adam Curtis' new documentary HyperNormalisation: http://www.bbc.co.uk/iplayer/episode/p04b183c/adam-curtis-hypernormalisation

Very good quality documentary as usual Adam Curtis standard, but one idea caught my attention. With all the AIs and machine learning algorithms on the internet, you are more likely to see things you already agree with. And if you voice your opinion on internet, it's more likely to reach those who already agree with you, thus have no effect on the idea you are trying to spread.

As AI improves, it will only get better at finding things match your interests. Would that mean it will reduce your chance of finding and accepting other opinions, and lock people to their own divided groups?
