I&#x27;d dispute that.  The human brain is, according to Marvin Minsky, a big bag of tricks, and we&#x27;re finding ways to replicate those tricks one by one, including really difficult things like planning and vision.  There are fewer left than you might think.  I told my friends in 2007 that we were 20 years from true AI, and I&#x27;m standing by that now; I think we&#x27;ve got 10 to 15 years to go.
