Imagining two apples is a different thought from imagining one apple, right?
I mean, is it? Different states of the whole cortex are different. And the cortex can’t be in a state of imagining only one apple and, simultaneously, be in a state of imagining two apples, obviously. But it’s tautological. What are we gaining from thinking about it in such terms? You can say the same thing about the whole brain itself, that it can only have one brain-state in a moment.
I guess there is a sense in which other parts of the brain have more various thoughts relative to what cortex can handle, but, like you said, you can use half of cortex capacity, so why not define song and legal document as different thoughts?
As abstract elements of provisional framework cortex-level thoughts are fine, I just wonder what are you claiming about real constrains, aside from “there limits on thoughts”. because, for example, you need other limits anyway—you can’t think arbitrary complex thought even if it is intuitively cohesive. But yeah, enough gory details.
On the other hand, I can’t have two songs playing in my head simultaneously, nor can I be thinking about two unrelated legal documents simultaneously.
I can’t either, but I don’t see just from the architecture why it would be impossible in principle.
Again, I think autoassociative memory / attractor dynamics is a helpful analogy here. If I have a physical instantiation of a Hopfield network, I can’t query 100 of its stored patterns in parallel, right? I have to do it serially.
Yes, but you can theoretically encode many things in each pattern? Although if your parallel processes need different data, one of them will have to skip some responses… Would be better to have different networks, but I don’t see brain providing much isolation. Well, it seems to illustrate complications of parallel processing that may played a role in humans usually staying serial.
Yes, but this is kinda incompatible with QM without mangled worlds.
