You are both missing the more important issue - signals cannot be decoded in the brain. It's tempting to think that is possible because we are living in a world of images on screens and in print, but these collections of pixels only cohere as images through our visual awareness, not through optical properties. Try thinking of any of the other senses instead - if instead of images, we want to peer into the decoding of digitized or analog signals associated with the smell of bacon cooking, would we set up a universal kitchen which would mix the aromatic compounds to match the tiny kitchen in the olfactory cortex? Can you not see that you still need a feeling, sensing person to smell the bacon or see the images? Otherwise there is no 'decoding'. The fundamental problem is *always* going to be the Explanatory Gap. When we talk about signals, we are already talking about awareness. The idea of a brain that can only recognize some small number of objects and tell if they are moving or not is the level of recognition which already exists on the level of an atom. T-cells recognize other cells and molecules. These kinds of sensitivities do not require a brain, they are everywhere, on every level.
