When I was working on a PhD, the Language of Thought theory (LoT) was everything. They wanted me to work on physical symbol systems, mental contents, and other computation-like models of cognition. But this much was clear to me even then: "there is no evidence of a genuinely digital code in the brain, or of a computer-like programming language being executed within the brain, let alone digital processors including the special components that are needed for processors to work, such as program counters or digital memory registers separate from the processors." So it's upsetting to me that people still talk as though the brain is like a computer with input processing, decoding, buffers, working memory, and the like.
