Is the Turing's "imitation Game" a Valid Test of Machine Intelligence?

Is the Turing's "Imitation Game" a valid test of machine intelligence?

Turing's description of the test: The test consists of having an interrogator in a room separated from a machine and a person on a different room. The game's goal is to have the interrogator determine which of the other two is a real person and not a machine. The person playing the role of the interrogator knows the person and machine by labels "X" and "y", but initially does not know which is which. The interrogator will ask questions to X and Y like the following example: "Will Y please tell me if Y is good at playing chess?" The objective of the person is to help the interrogator figure out which of the two the machine is; the objective of the machine is to make the interrogator think the machine is the person.

My personal belief is that the test is not sufficient, or maybe not be that relevant. The important thing is for the computer to show cognitive ability, the behavior of the computer itself is not as important. Simply put there are humans that would get confused during the imitation game and give a wrong answer. The test is not really complete, it cannot be determined if a computer is intelligent or not by that test alone.

Consider the blind's man bluff, and experiment similar to the Turing test, where a person born blind with some preparation can pass the test by playing a "lying game". The blind person imitates the answers of a sighted person, having not ever felt what is like to see. This experiment could show that a computer can pass such test by having an absence of consciousness. Turing didn't really stated that his test could measure intelligence, he knew that defining how humans think was very hard and wanted and alternate way of measuring if a machine could thing and find different ways to further the research on the matter. On top of everything, to correctly fool the interrogator I suppose the machine would have to copy or resemble some human behavior that is not intelligent like being susceptible to insults or maybe just making type mistakes. If the machine in question does not act somewhat unintelligently then it probably will fail the test.

It seems that if you have a machine that passes the Turing test, then you'll have that a machine that passes the test and tries to appear intelligent. A test for intelligences
