Off-topic, but I think we should stop calling them bubbles as they are getting larger and longer-lasting. It's more like they are domes, which don't pop easily. You've got people lying to poll-takers, rage-bait videos of people pretending to believe things they don't, trolling as a lifestyle, shared culture based off of weird beliefs... people can get away with avoiding truth and reality for longer than they used to. They can have happy lives doing it. It's a huge societal shift that I don't think has been properly analyzed yet.
