That is without a doubt impressive, the last time I saw a walking robot they were still very awkward on their movements while this robot has very fluid motion, however as people have said any robot like this that could replace humans is still decades away if not even farther, the real problem is with AI that does not need an impressive hardware like this, a soft AI that can only do one thing could be enough to get rid of millions of jobs around the world and I think we are getting close to that point as business want to develop it to avoid to have to pay their employees and improve their profit margins that way.
