As others have commented, the author doesn't seem to understand that computers as Information Processors is also a metaphor. Computers just shuffle electric signals around according to the properties of their circuits. Software is just an abstract way of referring to electricity flowing in a certain way inside the computer. My knowledge of how computers work is fairly shallow and my knowledge of neuroscience is basically none. With that caveat: this answer https://www.quora.com/Is-the-human-brain-analog-or-digital https://www.quora.com/Is-the-human-brain-analog-or-digital best fits my biases/intuitions. TLDR: The brain has a digital aspect -- neurons fire and send a signal or they do not -- and an analog aspect -- whether or not a neuron fires depends on the chemical(?) conditions in which it's embedded and inside the cell. This makes sense to me. That being said, I'm not sure whether I actually disagree with the author. If anyone is trying to find the brain's equivalent of a CPU, that's a fool's errand. It also seems likely that digitizing a brain is not possible, certainly not feasible. Digitizing analog systems is always(?) lossy -- the lossiness just doesn't matter with things like music due to the limitations in human hearing. This doesn't mean we can't create artificial brains, it just means that they can't be digital machines. My personal, bad, metaphor for memories is that they work somewhat like linked lists. It's easy enough to recite a poem start to finish. Harder to recite it if you start in the middle. Really hard to recite it backwards. Is this true? Who knows. Does it tell us anything about the underlying mechanisms? Not really.
