IMO, I think that frictionless experience comes at us from a bunch of angles - finding yourself in an echo chamber (by choice or not) online means that you may find yourself less comfortable talking with people you don't agree with, things like that. I grew up in a small town pre-social media, and that meant I didn't have much of a choice about who I was surrounded by. If I was growing up today, what would stop me from retreating to a comfy social media-mediated environment without any challenge or friction? If I was growing up 5 years from now, what would stop me from retreating even further to the comfort of my LLM "friends" who can be shaped to me perfectly? That world sounds terrifying to me.
