I do take your point. But the point I’m trying to emphasize is that the brain isn’t like a hard drive that fills up. It’s a muscle that can potentially hold more.
I’m not sure if this is in the Wikipedia article, but when I last read about this, years ago, there seemed to be a link between Hyperthymesia and OCD. Brain scans suggested the key was in how these individuals organize the information in their brain, so that it’s easy for them retrieve.
Before the printing press was common, it was common for scholars to memorize entire books. I absolutely cannot do this. When technology made memorization less necessary, our memories shrank. Actually shrank, not merely changing what facts to focus on.
And to be clear, I would never advocate going back to the middle ages! But we did lose something.
There must be some physical limit to our cognitive capacity.
We can “store” infinite numbers by using our numeral system as a generator of sorts for whatever the next number must be without actually having to remember infinite numbers, but I do not believe it would be physically possible to literally remember every item in some infinite set.
Sure, maybe we’ve gotten lazy about memorizing things and our true capacity is higher (maybe very much so), but there is still some limit.
Additionally, the practical limit will be very different for different people. Our brains are not all the same.
I agree, it must not be literally infinite, I shouldn’t have said that. But it may be effectively infinite. My strong suspicion is that most of us are nowhere close to whatever the limit is.
Think about how we talk about exercise. Yes, there probably is a theoretical limit to how fast any human could run, and maybe Olympic athletes are close to that, but most of us aren’t. Also, if you want your arms to get stronger, it isn’t bad to also exercise your legs; your leg muscles don’t somehow pull strength away from your arm muscles.
> your leg muscles don’t somehow pull strength away from your arm muscles.
No, but the limiting factor is the amount of stored energy available in your body. You could exhaust your energy stores using only your legs and left barely able to use your arms (or anything else).
If we’ve offloaded our memory capacity to external means of rapid recall (ex. the internet) then what have we gained in response? Breadth of knowledge? Increased reasoning abilities? More energy for other kinds of mental work? Because there’s no cheating thermodynamics, even thinking uses energy. Or are we just simply radiating away that unused energy as heat and wasting that potential?
