Memories are very personal things, over which we feel an intimate sense of ownership. Some people, such as spies, are sworn to secrecy over this or that incident, but, as one event or another washes over us, we typically aren't responsible one way or another for them. They are the historical cloth out of which we are cut. They are what makes us who we are.
"Today's robots are very primitive, capable of understanding only a few simple instructions such as 'go left', 'go right', and 'build car'." --John Sladek
