Very nice explanations about the AI and how it works in different areas of the word and scenarios. It is similar to human intelligence. If a person can learn how to drive in London, he could learn how to drive in Shanghai or Beijing. Same with AI - it just needs different experience (data, videos) to train with. More important, the same skill would be used to train other robots. They also work with a lot of visual data. Instead of turning the wheel and accelerating, they move hands.
