The thing I was alluding to is that people who study cognition itself are working with the people trying to create AI brains.

The two fields of study are really starting to talk to each other.
Sure most of it is imitative at this point, such as the stillwell brain experiment above.
Given that additive feature of our ability to learn and study this, and the number of people working on it, suggest we will get there. I get what you are saying. It won't be easy by any stretch.
I don't by into the Skynet type hype. People breathlessly predicting this stuff for clicks are doing a disservice to what is actually being done.
At some point though, and I would guess within my lifespan, we will have a conscious program/machine. I think we need to start thinking well in advance of this, what the ethical implications are. Do we let it vote? If a machine truly is aware and testibly conscious, could we turn it off? What rights would such a being have? Should such a being have?
