Common sense and nonsense

While reading something about the challenges of Artificial General Intelligence (AGI), which I was trying to understand more deeply than just scanning through, I fell into a rabbit hole of concepts:  common sense, critical thinking, reasoning (inductive, deductive and abductive).  Then I tried to connect that to my ongoing focus on understanding knowledge graphs and the organizing principles and schemas that are meant to organize data so that machines can "understand" and even generate new insights.  More and more, I am inclined to go back to an earlier interest in neuroscience, which I never pursued very deeply, but which informed some of my thinking.  Understanding how we, as humans, process information, how we learn, could be critical to the development of AGI, but it's not clear to me that we should try to replicate our brains. Common sense isn't that common after all.  

I stopped there because this is way too big of a topic for a little blog post and I will only embarrass myself with nonsense. There is indeed a danger in reading broadly and then trying to write in the absence of deep knowledge and understanding.
