I agree that they are high bandwidth inputs but not all of it sticks. There is a saying that goes: "in one ear and out the other". Recently, I learned about "reticular activating system". As far as I can understand, RAS determines what is important to you and provides your focus there. This is pure speculation but it might be that, eyes/ears are indeed very high-bandwidth inputs that if all their data was persisted, it would overwhelm our brain.
