Machines (Humanly Constructed Artifacts) Cannot Think

Well, I have an answer to this one, at least. Humans are machines


We don't know that. Of course it is a good default hypothesis as we don't have evidences for the contrary (except the wave collapse, but we don't have evidence for a wave collapse, actually).


- are, in fact, humanly constructed artifacts - hence whether machines can think is the same as whether humans can think.

Well, obviously, Turing addressed the question of human made machine ... by hand. he was a bit naive as he thought that it would take 50 years for a machine to pass the test (if I remember well).

But the test is a bit ambiguous. And if it does not last long, I can argue that a non thinking machine could pass it too. In fact Turing's approach here is a way to avoid the "hard problem of consciousness" (which is just the antic mind-body problem).

I am glad people learn more about Turing who was a great guy. Like Copeland and Turing's mother, I am far from sure he commit suicide. It would be nice if Emil Post, Kleene, Church and others were also celebrate. The movie "imitation game" does not seem to mention the main discovery of Turing: the universal machine/numbers alias the (universal) computer. I have not (yet) seen it.

Has anyone seen "The Imitation Game" by the way?
