How does the next
generation come to know who we are and what we have learned? Our wisdom, our
knowledge — our very selves, if that were possible — need to be
passed on. In doing so, it is thought, we give our own lives meaning. On their

will somehow “live on” in the memories of those with whom they interact. That
hope is illusory: human memory degrades with astounding rapidity.

electronic data storage appeared to provide a solution.
