"I went [to the top of] Vehicle Assembly Building and looked down, and tears burst from my eyes. The size of this cathedral where the Rockets take off to go to the moon is so amazing."

Talk about passing the Turing test - this device could give the test!
| I hate it when he asks the same questions I ask myself. "Rob, you aren't very responsive today," Sigfrid says through the little loudspeaker at the head of the mat. Sometimes he uses a very lifelike dummy, sitting in an armchair, tapping a pencil and smiling quirkily at me from time to time. |

In 1966 Joseph Weizenbaum published Eliza. A very short program (only a few hundred lines of code), was remarkably successful in creating the illusion of a computer psychotherapist. It works in a simple way; if the user mentions "I feel sad", Eliza might reply "Tell me more about feeling sad." Eliza worked by turning the user's question or statement around and giving it right back. This program succeeds for the same reason that that traditional talk therapy succeeds - people love to talk about themselves!
Want to talk with a real Sigfrid von Shrink? Go see ELIZA, the Computer Therapist. Just type your comment into the Input box and press return after each brief sentence. To readily see the limits of this approach, try typing something like "I feel asdfasdf" and see what you get.

Ever wonder how you look when you enter a new part of a spacecraft?
'Whoever launched it fired a laser cannon...'
'Most of the crew have the tiny imp ride on their shoulder...'
'About a third of the people in Manhattan have replaced their Freedom Card with a radio-frequency chip...'
