Turing Test

If a human being cannot distinguish between a machine and a human through interaction, then that machine would be intelligent.
The experiment that is visualized runs like this.In one room, there is a computer.In another room, there is an interrogator and a computer with a human and both the computers are are connected. The interrogator interacts with both the computers. He tries to guess which computer is run by a human and which is running by itself.
When the computer manages to fool the interrogator into thinking that it is a human, that is the point the intelligent machine is born.
Despite the spectacular advances, no machine has come anywhere near passing the Turing Test.
