Claiming that a robotic hand manipulating an apple is always a “specialization” of a robot grasping a red ball oversimplifies reality. The hidden cost of this simplification is that we might miss a more versatile solution if we focus too quickly on a single task. For example, if the goal is to sort objects of very different shapes and rigidities on a production line, a ball is actually a more general and more useful test to evaluate the robot's capacity than limiting it to a single type of fruit.
