Well, it was successful with monkeys in the 60s or 70s, whenever they tested it. Then made it illegal. So I'm interested to see the results of this experiment and how people react to it.
Seriously, this is amazing stuff! The fact that the one thing (aside from ethics) holding something like this back is the fusion of the spinal cord is just amazing to me. So, what he is saying is that if we were able to figure out how to re-fuse that spinal cord, this could occur?
Edit: Question to anyone: what are the ethical problems people have with this?
