Quentin Hardy has some interesting thoughts on what happens in a world of perfect recollection in his essay What’s Lost When Everything Is Recorded:

There is much to be gained from storage, of course. Who would not thrill to hear Lincoln at Gettysburg, or Shakespeare playing even a lesser role at the Globe? But Shakespeare’s plays were also reconstructions from the memories of diverse actors, some years after a performance. Our greatest literature was generated by an imperfect collective recollection, as much as it was written by one person.

I wrote about this issue before in The unnecessary fear of digital perfection.
