On Intelligence

I've just started re-reading On Intelligence, the book by Jeff Hawkins. I read it for the first time approximately four months ago. His ideas on how the human brain works are profound.

In the first chapter, Hawkins dispels Artificial Intelligence and the reasons why he believes it has failed. Basically, the human brain works differently than computers. As a result, computers are not intelligent by their very nature. Instead, we must first understand how the human brain works; particularly the neocortex. The first chapter also lays out that "... understanding cannot be measured by external behavior... it is instead an internal metric of how the brain remembers things and uses its memories to make predictions."
