By troubling things I guess you mean the "ok, I will destroy all humans."
It doesn't seem like this model is very capable of getting around on it's own, and it stated that talking was it's primary function. Some of those facial expressions in the second video look a bit goofy, but that's a pretty awesome robot for sure.
Can you imagine walking down the street and looking over at what you think is another pedestrian, but it's actually one of these robots waving and making goofy faces at you?
