Certainly, training AI for visual object recognition is a first useful step, but it isn't enough for a robotic hand to manipulate an apple without breaking it. Missing are pressure sensors and haptic algorithms to adjust force; otherwise, we risk damaged fruits, which is a pure waste. Visual information alone is a limited resource when it comes to physical precision; other systems are needed to complement it. Without these additional resources, even if we see the apple, the result might be the same as dropping it on the ground.
