On the subject of computers as metaphors for the mind, here's some cool facts:
Most people assume "machine language", assembler, is the lowest level.
While the whole processor does work with binary transistors on a low level, If you try to program a modern computer in machine code, you will only be accessing a higher level where it interfaces with the common architecture (be it x86, ARM, Risc, etc...).
All modern processors are designed by algorithm (not quite A.I in most cases, but some use neural networks) and have a massive inaccessible and barely comprehensible structure, that then translates its output to the known architecture machine code.
You can only communicate with it indirectly.
