Cybernetics is behind all modern AI (Turing was a cyberneticist), and also modern cognitive science with the ideas close to hybrid computing, neuromorphic computing, enactivism, embodied minds etc. Basically, cyberneticists were functionalists - and that allows for multiple realizability.

At the core of the book is the question of consciousness and qualia (and I do believe that a walkthrough through computational complexity is necessary, especially taking into account TIME and SPACE for both human neural processing and artificial one, differentiating between being incomputable in principle, being incomputable in practice or being tractable.
