Indeed. Imagine an 8 foot tall version coming at you. Tanks of the future?
I wasn't speaking about "robot world domination". That implies intelligent machines and this is not. But it looks like this one is pretty efficient in recognizing obstacles, and shapes. Once they can recognize targets, humans just need to deploy them and they will be much more efficient, without the need of human pilots. And they can come in different sizes and shapes.
I find it quite scary, and the DARPA logo at the end of the movie does not help.
