The key is how the AI uses its memory. The computer's controller is figuring out how to use memory as it goes along -- it's learning how to get ever closer to the correct answer without being explicitly told how to get there. A typical neural network wouldn't even have that memory to work with, so it either wouldn't hold the information or find a general way of reasoning that translates to different circumstances.

This wouldn't just be useful for navigation. You could ask the computer to identify relatives in a family tree using only basic knowledge about the relationships, or solve intricate puzzles with varying goals. All told, the very potential of neural networks is about to expand. You could see AI applied in situations where it was previously impossible.
