Is Emin right? In a world where we spend an increasing part of our lives staring at screens, could Digital Art give us a moment to "think about things we feel"? Can it rescue us from the constant commerce by communicating to us in the medium of our time, or is Digital Art simply a poor substitute for The Real Thing?
I thought I knew Damien Hirst. The one who puts dead animals in formaldehyde. Made a skull of diamonds. Did some things with coloured dots. Made me think: "Modern art? Rubbish. Anyone could do that." Well, turns out I was wrong. The current Tate Modern retrospective has changed my mind - and made me something of a fan in the process.
