I recently listened to an NPR program on computer-human interaction that a friend sent me.(You know I don't listen to NPR for fear of getting angry at their perpetual Jew hate.)
The program was good for the first half-hour as it summarized the state of computer-human interaction. The second half entered the realm of speculation that requires intelligence and that was not available to NPR.
It raised for me the issue that I had given serious thought to 30 years ago.
NPR concluded that a modern Turing test to distinguish a computer from a human being was based on a panel of people being deceived by responses where the computer was confused with the human 25% of the time.
The Phillips equivalent to the Turing test is an animatronic model of Abraham Lincoln with a full database of everything Lincoln was known to have said or responded. I assume that such a model is not far off in the future and will be completely satisfying to nearly all interrogators.
In response to this model I concluded that the issue is not whether a computer can be distinguished from a human the question is whether the human is alive.
Consequently I was forced to define alive as meaning the ability to be spontaneous.
My logic led me to conclude, thanks to the modern computer, that a large percentage of human beings are not alive. They aren't spontaneous and they may not be capable of spontaneity. The technical term is zombie.
