Its incredible, this is going to give hope to a lot of people who have suffered injuries which have changed them forever. However i feel this technology is going to be out of reach of everday people for quite a while simply due to the cost factor.
It's amazing how something that should be so critical among uses of technology could be reduced to little more than an afterthought. Of course bionic legs are important. In fact, they should be a priority as far as society's concerns and use cases for a smarter world filled with embedded applications for everything. We try to make driving and cooking and other things marginally better for most of us when we could make something as fundamental as walking a whole lot bette--or should I say possible in the first place--for a few of us.
This is a very good news for people who are in need. More companies should do their production and can be made economical and made available at the nearest chemists shops. This is another way to make people happy who are unable to do the basics things in life just becuase they have lost some parts.
