In chapter 3 of Sherry Turkels
book "Life on the Screen", the author starts of with a comparison of how
the children of today react differently to computers than children of twenty
years ago. Turkel begins by stating that "until the advent of the
computer, children who became facinated by technology could have thier
interest held by the promise of understanding a mechanical system.
What this means basically is if a child wanted to learn how a toy worked
he or she could always take it apart because usually the internal mechanisms
were fairly easy to understand. Some examples would be erector sets,
model trains and Legos although the latter really had no internal mechanisms.
With the advent of computers
children began viewing them psychologically. What this means is that
even if a child opened up a computer to see the internal workings, chances
are they wouldn't understand what was going on. Therefore the children
would think of the computer as somthing with a mind.
Later in Chapter 3, Turkel begins
on the idea of intelligent machines. Turkel points to the "Turing
Test", this test was devised by mathematician Alan Turing as a way of testing
whether a computer could pass for human. The Turing test is simple
enough, a person asks a question through a computer terminal and receives
responses via the terminal. If the person feels that they are talking
to a real person rather than a computer than the machine is intelligent
an thus passes the Turing Test. Later in the Chapter, Turkel points
out that the Turing Test came under heavy fire from philosopher John Searle
who said" true understanding could never be achieved by a computer program,
no matter how clever, because any program simply follows rules and thus
could never understand what it was doing.
Finally, in the last part of
the chapter Turkel gives the reader a humorous example of how one person
was fooled by a computer program. The computer program was named
Julia and was actually a bot designed to go on a MUD or multi-user domain
and give the impression of being human. Turkel lists many encounters
a human player named Barry had with the bot Julia. Barry was totally
fooled for months into believing that he was corresponding with an actual
human. To be perfectly honest, after reading the dialogue between
Barry and Julia, I admit I probably would have been fooled also.
