Geek stuff, sci-fi... The Cambridge University mathematician laid the foundation for the invention of software. As part of its anniversary celebration, BusinessWeek is presenting a series of weekly profiles for the greatest innovators of the past 75 years. Some made their mark in science or technology; others in management, finance, marketing, or government. In late September, 2004, BusinessWeek will publish a special commemorative issue on Innovation. Elsewhere, there is also a special article for Turing.

RE: Alan Turing and the "Turing Test"

Essentially what he argued was "if it looks like a duck and quacks like a duck, and you are fooled into thinking it's a duck, it's duck."

What he argued was that if a machine can behave in ways indistinguishable from a human being under intense interrogation, we should seriously consider the possibility that the machine is thinking. He never argued that the machine would be a human (to follow your analogy) and indeed he spends 2/3rds of the paper ("Computing Machinery and Intelligence") discussing the objections to the initiation game, including the possibility that the machine could fool the interrogator without actually thinking.

But, no matter how good it looks and no matter how completely it fools me, it's a photo.

Then it fails the imitation game. The whole point of the game is to convince the interrogator that the machine is thinking. If he isn't convinced, the machine loses. If your photo doesn't convince you that it's a sunset, it loses.

Realistically, the photo is always going to lose the game. Real sunsets produce light and heat and are visible from many locations. In order to imitate a sunset, the photo would have to reproduce all the properties of the sunset that people use to determine it is, in fact, a sunset. Fooling one person, one time, in unusual circumstances isn't sufficient.
