alt Hacker NewsThe Turing test and Searle's "rebuttal" are both pretty inconsequential. There's no real definition of "thinking," therefore neither proof/disprove or say much.
Turing's imitation game is about making it difficult for a human to tell whether they are communicating with a computer or not. If a computer can trick the human, then... what? The computer is "thinking" ?
I think most people would say that's an insufficient act to prove thinking. Even though no one has a rigorous definition of thinking either.
All this stuff goes around in circles and like most philosophy makes little progress.

Searle’s rebuttal is actually excellent philosophy. But otherwise I agree. Searle was (just learned he passed away last year) a philosopher by trade, but Turing was a mathematician and Schrödinger was a theoretical physicist. So it is to be expected that a mathematician and a physicist might produce sub-par philosophy.
Turing’s point in his 1950 paper was actually to provide a substitute to the question of whether machines could think. If a machine can win the imitation game, he argued, is a better question to ask rather then “can a machine think”. Searle showed that this is in fact this criteria was not a good one. But by 1980 philosophy of mind had advanced significantly, partially thanks to Turing’s contributions, particularly via cognitive science, but in the 1980s we also had neuropsychology, which kind of revolutionized this subfield of philosophy.
I think philosophy is actually rather important when formulating questions like these, and even more so when evaluating the quality of the answers. That said, I am not the biggest fan of the state of mainstream philosophy in the 1940s. I kind of have a beef with logical positivism, and honestly believe that even Turing’s mediocre philosophy was on a much better track then what the biggest thinkers of the time were doing with their operational definition.

If you read his paper, Turing was trying to make a specific point. The Turing test itself is just one example of how that broader point might manifest.
If a thinking machine can not be distinguished from a thinking human then it is thinking. That was his idea. In broader terms, any material distinction should be testable. If it is not, then it does not exist. What do you call 'fake gold' that looks, smells etc and reacts as 'real gold' in every testable way ? That's right - Real gold. And if you claimed otherwise, you would just look like a mad man, but swap gold for thinking, intelligence etc and it seems a lot of mad men start to appear.
You don't need to 'prove' anything, and it's not important or relevant that anyone try to do so. You can't prove to me that you think, so why on earth should the machine do so ? And why would you think it matters ? Does the fact you can't prove to me that you think change the fact that it would be wise to model you as someone that does ?
