Actually this may not be so lazy, Well, not for the crippled-below-the-waist community... With this new technology out they can do much more with it, new motorcycle prototypes, new mobility system instead of prosthetic spoon-looking leg things, and probably so much more, tons I could list but I don't have the battery left to finish.
But just think about it and embrace it instead of rejecting it and putting it down.... You can never truly know where technology such as this could lead.
