The central paradox of the machines that have made our lives so much brighter, quicker, longer and healthier is that they cannot teach us how to make the best use of them; the information revolution came without an instruction manual. All the data in the world cannot teach us how to sift through data; images don’t show us how to process images. The only way to do justice to our onscreen lives is by summoning exactly the emotional and moral clarity that can’t be found on any screen.
