No I don't see why people would want to become more intellectual. What's the payoff for the effort?
People are lazy, at least the majority are. Then you have the personality types that needs to compete, and they are very useful in positions where you work hard all day to get a pat on the back. But they are more rare. Most of us don't see a reason to be intellectual or to compete, even if we have the capacity.
Because there is nothing that matters anyway. If we were living in a star trek society where we all contribute to a common good and gain respect from the community for it, then we would be motivated. But this is the stone age... Raw capitalism. History books will be written about this age and how pointless it all was.
