Now, I've got a shard of glass here, OK.

What we're left with is a collection of five million books, 500 billion words, a string of characters a thousand times longer than the human genome a text which, when written out, would stretch from here to the Moon and back 10 times over a veritable shard of our cultural genome.

Maybe many of you have noticed this with loved ones, you can find somebody who can't recognize their face in the mirror, or can't tell anyone in their family, but you can still find a shard of music that that person will jump out of the chair and start singing. And with that you can bring back parts of people's memories and personalities.
