I'm not sure what you mean by "a shared experience with unmediated interactions." Without mass media, how did people share an experience? Do you mean sharing with your friends/family/church? If so, isn't that option still available post-transition? Or is your point that social media destroys personal interactions, so the next generation is left with nothing (kind of like porn destroying healthy sex lives)? If so, then I agree the future might be worse. But it's also possible that social interactions are changing, and it is only because they are different for us that we think of it as "worse". Moreover, society hasn't yet had a chance to adapt to the new technology, so we don't know exactly what social interactions will be like in the future. It could be that kids tomorrow will learn to adapt to social media just as our generation learned to adapt to TV.
