except we aren't talking about internals of the brain - we are talking about definitions of the words, which are very different

The definitions of the words are contingent on human experience, even more so than "code" are "data" where we try to be more mechanistic, and still most people make the mistake of thinking they're distinct categories (spoiler: they're not; whether something is "code" or "data" depends entirely on your perspective).

If we want to draw computing device analogies, then the brain is an FPGA that is continuously reconfiguring itself throughout its runtime.
