The unclear sides of the implementation are just the usual normal hurdles on the path. There are no impacting doubts about the goal.

The point was, let me remind you, that we do not see any need for biomimicry: we did not need to simulate any brain to implement counting. Similarly, there is no need to simulate a brain to implement a reasoner (and the problem is well defined).

They are just occasional events in the whole history of the endeavour.

...or, in other words: "yes, if we had the recipe, it would be trivial". Yet we normally manage without.
