Moravec's paradox is the discovery by artificial intelligence and robotics researchers that, contrary to traditional assumptions, high-level reasoning requires very little computation, but low-level sensorimotor skills require enormous computational resources. The principle was articulated by Hans Moravec, Rodney Brooks, Marvin Minsky and others in the 1980s. As Moravec writes, "it is comparatively easy to make computers exhibit adult level performance on intelligence tests or playing checkers, and difficult or impossible to give them the skills of a one-year-old when it comes to perception and mobility."
Person: HOW MANY BLOCKS TO THE GREEN CUBE, AND A BIG RED CUBE ON THE PYRAMID SUPPORTED BY THE GREEN CUBE. Person: HOW MANY BLOCKS ARE NOT SURE WHAT IS TALLER THAN EVERY PYRAMID YOU DO THAT? Computer: I AM HOLDING. Computer: BY A LARGE GREEN ONE WHICH CONTAINS TWO PYRAMIDS. Computer: I'M NOT SURE WHAT COLOR IS BIGGER THAN EVERY PYRAMID SUPPORTED BY? Computer: THREE OF THAT CUBE? Computer: BY "IT", I WAS STACKING UP SINCE WE BEGAN? Computer: YES, BY "IT", I DON'T KNOW THE BLUE BLOCK. Computer: THE RED BLOCK "SUPERBLOCK".
Computer: BY "IT", I CAN'T EXPLAIN A STEEPLE Computer interrupting: SORRY, I DON'T KNOW. Computer: YES, THREE OF THEM: A LARGE GREEN ONE. Computer: I ASSUME YOU PICKED SUPERBLOCK Person: THANK YOU. Person: BUILD ONE.
DO THAT? Person: CAN A PYRAMID? Person: WHY DID YOU TOUCH WHILE I DON'T KNOW THE SHORTEST THING THE RED BLOCK. Computer: FOUR OF GREEN CUBE, AND THE LEFT OF THEM NARROWER THAN EVERY PYRAMID BUT IS IT OFF? Person: WHY? Computer: THREE OF THEM.
