A subject that my mind has been unreasonably fascinated (dare I say fixated) on recently is this; no one really knows why we yawn. There are theories, of course — from one’s blood containing increased amounts of carbon dioxide in need of release to a body’s way of controlling brain temperature. Especially elusive is why it seems to be contagious. There are many theories but no definitive answer.
Something as common and basic as yawning is a mystery and I love this. I love such known unknowns. It seems like there should be a simple explanation for such a common benign thing , and yet it alludes even the minds of science.
This is true of many things, especially when it comes to the brain and human behavior. We know more about the far reaches of the universe than we do the depths of our own mind. This gives me a great comfort. I can’t really explain why. The best explanation is it makes me feel human.
Which leads me to wonder about the limits of artificial intelligence…
Because, as far as I understand it, it can only ever know what we know. Perhaps it can take all the disparate pieces of our knowledge and see connections and come up with new ideas and solutions based on these that we humans would be otherwise limited to. But, those limits of human knowledge correspondingly are the limits of AI. AI may be able to beat us in collective capacity and perhaps even speed of understanding, but its knowledge, or lack there of, is ours.
AI can’t tell me, definitively, scientifically proven and agreed upon, why we yawn. And it won’t be able to until we humans can begin to answer that question ourselves. Until we take all of the theories, do all of the testing, run it through scientific methods, and be able to say, with an overwhelming level of certainty, “We yawn because…”
So, this puny human will continue to obsess over and be delighted by the mysteries of our amazing brain and rest in the comfort that AI doesn’t know any more than we do.
