I don't think it's necessarily aversion. I think people are fundamentally not learning how to have human conversations. It's kinda wild how often at my job I just have to fully take over a call and handfeed the person on the other end information, because if left to themselves they'll just kinda fumble around confused at the concept of asking the question they called to ask. If you don't know how to make a phone call, it's not surprising that you wouldn't ever want to.
