I think the feat is more about physical engineering than the "AI", albeit it is impressive that they have software that can keep it upright at such speeds. One issue if you look at nearly all the humanoid robots is achieving anything like the speed of humans from motors you can fit in the humanoid shape, even the ones that can do the dance moves and the like tend to look like a bad Frankenstein monster when it comes to walking and running. The Chinese are so far ahead of anyone else in robots that is hard to see any way they won't dominate the market, if such a market exists. (That is a big if.)
