*shrugs* Would still say that, correct or not, that still describes something better than what was before it. Even with the "gated communities" of the internet, you still get a lot of exposure to other views and whatnot, massively more than what insular societies would see just a few decades back. Before, it was entirely possible -- and damned likely -- to go pretty much your entire
life in one of those little ponds, except the ponds were defended often to the point of violence. You still have many places in the world, even with internet exposure, that are like that -- even in the goddamn US I've met what's probably dozens of folks now that's shared stories of spending twenty, thirty years, their entire formative years and much of their young adulthood, without ever meeting/getting within speaking distance or exchanging any words of note with, say, a liberal, or a hindu, or a black person, and talked to older folks that literally spent everything but the last decade or two in that kind of situation. Nevermind anything substantial or any "clashing or meshing", it just outright didn't bloody
happen.From just about everything I've seen over the last near-three-decades now, even the most echo-chambery and protected of internet echo chambers doesn't even
remotely approach how insular things can -- and pretty often
do -- get outside of it. The ease of communication and equivalent actions to movement, the general lack of reliance on conforming for
goddamn survival... stuff like that makes a genuinely massive world of difference when it comes to
mitigating those flaws that blurb was talking about. I'd say pretty strongly that if you think the internet exacerbates those flaws, you haven't seen much of their manifestation in the wild
