I'm glad that there are people out there thinking about these things. I've witnessed first hand some pretty amazing limb functionality improvements through nerve repair and definitely understand his confidence in that realm. However, I can't think of a scenario in which testing this really could be justified. The one that comes to mind first, of course, is a quadriplegic. But really, we'd be putting a real person through an incredibly traumatic procedure with a high likelihood of fatality for a chance at motility. I don't think there'd be much support for that.
