Disappointing.
Living tissue requires biological nutrition, thereby introducing new and additional design complexity. Living tissue would be susceptible to disease and aging, thereby introducing sustainment complexity.
I was hoping that the “living tissue” being referred to would actually be the elastomer plastic announced some years ago that would contract and relax in response to electric current. It sounded like a lead toward the development of artificial muscle fibers. That, of course, would be a tremendous development for robotics.
It could also lead toward greatly improved limb prosthetics that could be directly connected to the amputee’s nervous system. It would be better than Star Wars.
Check out Elon Musk's companies, Neuralink and OpenAI. Rather than connect to the nervous system at the amputation location, they insert smart implants into the brain "which could soon cure paralysis, deafness, blindness, and other disabilities". And possibly control limb prosthetics.
