I'm not surprised people look at this human-like and try to attribute human-like responsibilities. It'll be a marketing trap that many fall into.
But for now, the sensing, state estimation, and energy density problems preclude the use of these robots in the real world. There's far too much uncertainty in the structure of the world or the modelling of unknown areas to do parkour outside -- unless I've missed something huge that boston dynamics has done without talking about.
As someone said below, however, if you can develop a hybrid control scheme with a human controlling a smart-ish legged vehicle, you're on a roll. That's the future for legged vehicles that I could see: something like mechwarrior or titanfall, but without the AI (remote operated). Or Dreadnaughts. But small (as someone else pointed out).
