That’s closer, but I also think it’s wrong to look at the brain as a GPU of general mind stuff hooked up to a CPU of attention.
I think it’s likelier that each portion of the brain fires away at up to whatever its natural “throughput” is (some activities more or less parallel), and conscious awareness just happens to feel like a single global mutex.
I guess this is a game you can play where you keep refining the analogy until it’s too complex to help, but I don’t think the linked author’s analogy is good or useful. Better to just say we can’t be consciously aware of two things concurrently. It’s not a hard concept.
