I don’t know about you, but I sometimes worry that I spend too much time looking at screens: computer screens, smartphone screens, TV screens, movie theater screens, and (of course) screens on which slides are projected. Am I cutting myself off from the real world? Am I insufficiently mindful and overly mediated? Am I, in short, watching “shadows of artefacts” all day long, just like the prisoners in Plato’s cave? There are plenty of people who would say Yes, yes you are, you and all those other SXSW attendees. Get out of the dark cave of your parents’ basement, nerd, and get some sunshine. Stop with the fantasy already.
