Well, "they" have already decided that Nural Networks are the future of AI's deep learning.
Others have already working on Fish and Fly brains, oh and humnan brain matter been cultivated in the petri dish to the point that redimentary eyes develop.

So It must be on the road map for - if not already - organic nurons are used to recreate what we are currently seeing with this very basic deep learning AI.

The modern day equivalent of Asimovs Positronic Brain is on its way. :-) :-)
