I don't buy the argument because the world around us is build for human, we'd better build humanoid robots. Robots with belted wheels or 4 legs can handle stairs, ramps, uneven terrains well, easily and fast. Installing a couple of robot arms on it, you have much more robust robots. Spending so much effort just to solve the moving and balancing is a waste of money and talent.
It reads less like a review and more like a very high level overview. I was expecting a review and comparison of the capabilities of the leading humanoid robots under development. The author probably meant to use the Republic of Korea flag for Boston Dynamics, instead of that of North Korea.
