Smaller brain + equal or higher output = a more efficent brain based upon size. It would require less mass. Less mass results in many benefits.And why would a brain becoming smaller necessarily have ANYTHING to do with a brain becoming more efficient?
You make it sound as if people are to catered hand and foot by calculators that are capable of doing absolutely everything, and this is incorrect. I don't think, throughout history, that the average person had subjected themselves to much thinking anyways. That's probably why they're average. In any case, I'd like to see the proof that calculators have caused the brain to shrink. The idea seems outrageous to me.Let me clarify what I'm saying: The necessity of the average person to TAX THEIR BRAIN and use RAW BRAINPOWER (which results in the strengthening of neural connections) has been gradually reduced over time. We have computers and calculators now that can do everything for us. There isn't as much thinking that the average person is forced to subject themselves to on a day-to-day basis anymore, because so many things that previously required raw brainpower to perform are now automated.
Uh............Here's what I'm NOT saying, which is what you seem to have interpreted: I'm NOT saying that humans are no longer driven to learn and figure things out, no longer competitive, suddenly incapable of creating a developed education system, etc.
Except for the fact that the things continue to grown at a faster and faster rate instead of slowing down or coasting.That's a natural byproduct of compounding facts and knowledge that humans have amassed and compiled over time and not necessarily a reflection of us having better, more efficient brains now.
Har. You seem to be doing a good job of pioneering that nosedive. Just kidding. Har har har.I'm more curious to see the effects of the internet era on the brain and brain usage/function/problem-solving/thought processes 30-50 years from now. We're still in the relatively early stages of what is probably the most revolutionary technological discovery of all time, and not nearly enough time has elapsed to accurately analyze/predict how humanity will be affected. I'm predicting an intellectual nosedive as technology becomes more and more advanced and automated.
