>Will our willingness to look another human in the eyes, to feel anothers embrace, to laugh and dine with another with ease, will these all be things of the past at some point?

I dont believe so. Things like podcasts are only one facet that is being addressed. There is no interaction. No physical connection. Nothing but a screen to look at and a speaker to listen to. I think eventually, people who are heavily into this type of thing, will eventually look past the podcast or whatever it is and decide they want social interactions just like these podcast people had since they seem to be enjoying it. Or start a podcast of their own and that in itself is a form of human interaction.
