Lotus Operandi

Even Capital Records got to Sir John Lennon eventually. Behind a curtain, dating game style, they subjected him to the Turing test:

A computer and a human volunteer are hidden from John's view. Then John subjects both of them to questions and then, based on their answers, tries to determine which respondent is the computer. The computer is programmed to lie and try and convince John that it is the human and the volunteer is the computer.

Then the roles are reversed. John goes behind the curtain and another computer is brought in to ask questions and determine if John or the computer is the computer.

Representation of the primordial earth, about 4 billion years ago... Within another 500 million years, living cells would be present on the surface.

(During its formation, the moon presumably was closer to the earth. Here it looms on the horizon.)

The difference, then, is that it is possible for a machine to act unobservant. It is impossible for a human to act unobservant. If somebody says that some task is "mechanical", it does not mean that people are uncapable of doing the task. It imples, though, that only a machine could do it over and over without ever complaining or feeling bored.
