You go on to argue that the cortex is our most uniquely human brain part and arguably the seat of our most general reasoning abilities. But even if these are true, they don’t at all speak to the overall abilities of a system which only had the equivalent of a cortex.

### Indeed, but these arguments support the notion that general reasoning abilities should be achievable using a modular, relatively simple algorithm, rather than a horrendously complex one.

Okay, but I’m much less interested in “general reasoning abilities” than in full functionality to substitute for humans on almost all jobs.

If you put a deep neural network with 2000 layers on top of whatever powers ATLAS robots you could get a pretty close facsimile of a human mind in a clumsy human body.

Here you seem to claim that everything but the cortex is relatively trivial - that  we already have all those abilities modeled, and all we need is to add a cortex to have a complete system. THAT is the claim for which I’d like to see evidence.

### Yes, a lot of the complicated stuff outside of the cortex has already been realized in silico, but this doesn't make it trivial. ..
I would however venture that to make a true functional substitute for a human, rather than a copy just able to star in demo clips, AI researchers still need to perfect a motivation system that would fit between the AlphaGo optimization algorithm and the lower functions already embodied in existing robot designs. .. Maybe it won't be too difficult to use existing deep learning paradigms to implement complex motivation, going from robo-nerds to social butterflies, maybe new discoveries would need to be made. My guess is on the former but I am no expert in the area.

I’d say you really don’t know how many other modules are needed, or how hard they will be to create. But you do here admit that there is at least one further module needed that we don’t have or know how to make.
