I'm not saying that all, but I think that part of the solution will be finding ways to get people interacting with each other directly in more ways either through direct outreach (going door to door or talking to people in public) or civic engagement. You don't have to be exposed to everyone, I had some really positive conversations when stuck at jury duty last time. A lot of people just go find a corner to hole up in but I ended up sharing a corner of the courthouse with a group of people that preferred to chat and it was a really nice way to while away the time (we had a 2 hour discussion about gun control that was very civil and diverse in ideology which the internet would lead you to believe was impossible). I'm not saying any of this to detract from this tool or any of the other interesting tools linked here, I think its great to try to find as many solutions as possible but its just been my observation recently that humans interact best face to face, hopefully we can find a more scalable solution though.
