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," Sussman
replied.

"Why is the net wired randomly?", asked Minsky.

"I do not want it to have any preconceptions of how to play," Sussman said.

Minsky then shut his eyes.

"Why do you close your eyes?" Sussman asked his teacher.

"So that the room will be empty."

At that moment, Sussman was enlightened.
