It’s been a while since I read it. The main parts that stuck with me were about the approach of trying to map out brain structures and figure out what they do. Then implement these in a neural network and see if they produce similar results. This seems like the right approach for trying to figure out how to implement a biologically inspired AI. And the part about the 6 layered structure being repeated in the cortex is very encouraging. If it is a single repeating structure, then there’s a good chance we’ll be able to figure out the algorithm there.
