In the days when Sussman was a novice Minsky once came to him as he
sat hacking at the PDP-6.
"What are you doing?", asked Minsky.
"I am training a randomly wired neural net to play Tic-Tac-Toe."
"Why is the net wired randomly?", inquired Minsky.
"I do not want it to have any preconceptions of how to play".
At this Minsky shut his eyes, and Sussman asked his teacher "Why do
you close your eyes?"
"So that the room will be empty."
At that momment, Sussman was enlightened.
