No he didn't. I'm adding to his statement. Saying it's kind of a meaningless statement as meaningless as saying a car can go faster then a plane if the plane isn't moving.

A hard working stupid person can accomplish more then a smart person if the smart person isn't working at all. This statement is as obvious and insightful as the statement about the plane. And it sort of obfuscates the fact that smart people have a huge advantage in the fact that they have to work less hard.

Additionally despite all of this, there's no magical thing stating that all smart people never work hard. Smart people may in many cases even work harder than stupid people.
