Watched this one a while ago, the guy walks incredibly smoothly with them.
OT: Yes. Besides the fact that they would be superior to my biological limbs, i'd never have to go to the gym anymore, they'd probably have advantages like super zoom in artificial eyes, I could still walk normally even when i'll get old, no muscle pain, no skin burns, I could become taller if I want etc. Plus they'll won't degrade over time. I mean there's so many advantages, and if they manage to transform the energy from the food you eat to the bionic limbs so that you'll won't have to recharge them all the time i'd definitely get those limbs. You can also just put skin-like tissue over them so they look like just regular arms.
