Time and money are scarce resources, and focusing solely on image recognition is like buying a car engine without the wheels.
Without precise force sensors and integrated haptic feedback, the robotic hand could crush the apple, no matter how much AI "recognizes" it.
We can't afford to waste resources crushing apples just because we misjudged the prerequisites.
