Listened to this last night on Radio 4 as I'm a massive fan of James Bridle's work. Only 15 minutes so worth a quick listen here
"Publisher and technologist James Bridle asks how computer networks will affect cultural memories.
How will storing our memories and experiences on 'the network' change how we relate to them? They are no longer spread through time and geography, and instead much more visible to us, but what does that mean? When we have read a book, the book remains as a souvenir of the experience, but we do not yet have a similar way of accounting for the time we spend online."
And if you're interested in reading more about 'network realism' James has written previously on this here.
