Somehow I doubt any of us will ever be able to afford this anytime soon.
Seeing how we apparently have mechs now, there is probably already is a militarized version of this designed for actual dangerous situations. A giant robot would just be too much of a target on the battlefield, but it would be ideal for riot suppression, and those 'harmless weapons' could easily be swapped out for something genuinely dangerous.
A more benign use for this technology would be to assist handicapped people who can't walk on their own, or for heavy lifting, or even sporting events, but we all know that this new technology in fact won't be used in a beneficial way.
