Claiming that the robotic hand from Festo moving from a red ball to an apple is a specialization is a clear mode of failure in reasoning.
A ball is a perfect and rigid object, while an apple has texture variations and an intrinsic fragility.
The ability to manipulate an ideal object does not guarantee the delicacy needed for a fruit that can be damaged by the slightest shock, like a garden tomato.
The weak point of this statement is ignoring the complexity of the real world compared to a controlled demonstration.
