In the Alan Turing biopic, “The Imitation Game,” there’s a moment when an interlocutor asks Turing, a math genius, “Can machines think the way men do?” As Turing answers it becomes apparent there were really two questions in that query. One is, “Can machines think (at all)?” Second is “Can machines think in the manner of men?” (For the record, Turing’s answers are yes and no.)
So how do we humans think? I think (ha ha) that we believe we largely think in a sort of logical fashion, almost like a series of programmatic steps. We may think, “I’m hungry. I should go to the store to get a sandwich. It’s hot out so I will take the car.” And we do often think this way though we don’t really “think out” all the dialogue. For this kind of thinking we are largely consciously aware of what’s going on. We don’t suddenly find ourselves buying a sandwich for no reason.
But we are also aware that some of our thinking is subconscious. We muse upon a problem, decide to put it away or “sleep on it,” then suddenly a day later the answer appears to us magically. (I solved a particularly pesky VPN issue this way years ago.) It seems clear that some part of our brain was working on the problem without us being aware of it.
Buried in the dialogue in the Turing film is, perhaps, the idea that machines, specifically computers, can’t consciously think. They’re thinking is more like our unconscious processing.
Let me throw in an added complexity. Let’s say a guy looks at a beautiful woman and says, “I’d sure like to have sex with her!” It would appear he wants sex, as everybody does, and his brain is voicing a thought that occurs to him upon the appearance of a attractive mate. The thinking is all conscious. But we humans also have the idea of evolution and the notion that what really drives us is our cells’ desire* to pass on their genes. According to this idea, somewhere along the line there’s some kind of information processing (something like thinking) that says, “Ah, here’s a chance to pass on our genes. Let’s dupe this guy into thinking he merely wants to put his penis in this attractive female.” So there’s two levels of “thought” here—the guy’s conscious thought and some weird level of informational processing occurring well below the brain.
* Of course, we don’t really think cells are conscious in such a way that they can have desires. But on some level cells are driven to the goal of duplicating themselves.
Anyway, I don’t what to make of all this but thought (ha ha) I would put it down.
