As long as I see people with joysticks controlling the robots, I am not impressed. When the robots become the ones holding the joysticks, THEN I'll be worried.

The Japanese seem to have a cultural fixation on visually appealing humanoid robots. (Although I admit there's a bit of pragmatism to it, for their overwhelming need for nursing/elder-care) TRULY autonomous operation and on-the-fly navigation through random uncontrolled environments is present in the Japanese efforts, but is always kind of on the periphery, or back-burner.

And while the Japanese tend to put cosmetic mecha-looking armor on some of their robots, the U.S. has a tendency to put guns, bombs, and Hellfire missiles on ours.
