A Logic Gate Made of People

“I don’t know your names,” Von Neumann said, tapping the shoulders of two of the soldiers. “The two of you will be responsible for signal input, so I’ll call you ‘Input 1’ and ‘Input 2.’” He pointed to the last soldier. “You will be responsible for signal output, so I’ll call you ‘Output.’” He shoved the soldiers to where he wanted them to stand. “Form a triangle. Like this. Output is the apex. Input 1 and Input 2 form the base.” “You could have just told ...

This reservoir can scarcely be other than the subatomic energy which, it is known exists abundantly in all matter; we sometimes dream that man will one day learn how to release it and use it for his service. The store is well nigh inexhaustible, if only it could be tapped. There is sufficient in the Sun to maintain its output of heat for 15 billion years.

 Working with a Black Box Problem and Star Trek

The job of computer scientists, of course, is to design the programs that let electronic computers accomplish those impressive feats of thinking and knowing. The computer scientists have to figure out how to make programs that get to the right kind of output from the right kind of input. But our job as cognitive psychologists is rather different and even harder. We are more like archaeologists than engineers. Actually, it's a familiar Star Trek story. We have landed on a planet that already...
