&gt; you&#x27;re browsing through a catalogue of amazing experiences while you sit at home feeling a little fat.<p>No, I think it&#x27;s more than that. I have no evidence for this, but I suspect that spending excessive time on the internet will make you feel more isolated (and therefore worse overall), regardless of whether you spend that time on social sites or not. It&#x27;s the withdrawal from genuine face-to-face contact that is important, not the particular mechanics of such-and-such an app or website.<p>I think we&#x27;re still missing something important about human interaction in the way we embody it in computers. Even video does not solve it completely. Telepresence is and will continue to be a major open problem for the forseeable future.
