My experience has taught me this is just untrue. My various jobs have been 100% remote for the last 6 years, so being comfortable with video and voice calls is essential to that.

Going back to when I was a high schooler, I was closeted and in boarding school, which admittedly had a significant built-in social life (that was of little interest to me), but I was also able to have a long distance close friendship for years thanks to Google Talk. I dare say some of my most important and formative social moments in my high school years were over Google Talk with my small group of friends. Sure we had antics in the dorm at my boarding school etc., but these were minor and fleeting interactions versus the deep and meaningful relationships I had over Google Talk, and anyone I actually cared about at boarding school also interacted with me that way, a good bit.

there's nothing wrong with online from my perspective, but there is when it's the only form of interaction. If you only spend time online with your close peer group you're never exposed to content far outside of the norm, and you don't get a diversity of communication mediums. You are literally handicapping your ability to communicate.
