Computer pioneer Alan Turing’s remarks in 1950 on the question, “Can machines think?” were misquoted, misinterpreted and morphed into the so-called “Turing Test”. The modern version says if you can’t tell the difference between communicating with a machine and a human, the machine is intelligent. What Turing actually said was that by the year 2000 people would be using words like “thinking” and “intelligent” to describe computers, because interacting with them would be so similar to interacting with people. Computer scientists do not sit down and say alrighty, let’s put this new software to the Turing Test - by Grabthar’s Hammer, it passed! We’ve achieved Artificial Intelligence!
My impression as an atheist is that there is no special sauce that makes human intelligence impossible to achieve. It will happen eventually.
Our brains are computers made of meat. Nothing more. Our thoughts, our dreams, our consciousness itself is quite literally just chemicals, hormones and synapses instead of circuits, binary code and wiring. There is no soul that would prevent true life from arising once the computing becomes powerful enough for it.
