Saying that training an AI enables a robot to grasp an apple without crushing it overlooks part of the problem, because our resources are limited. It's a necessary condition, but not a sufficient guarantee; sensors, actuators, and especially the control code that transforms data into a delicate physical action are also needed. Without precise mechanics and fine-tuning of grip forces, even with millions of training images, the robot could very well turn the apple into mush. There are many technical details to be fixed on the robot itself; it doesn't happen automatically.
