Figuring out the required stem cell treatment to properly regenerate damaged nerves or creating some kind of non-degrading synthetic nerve that can be placed in the spine (or wherever) seems like a much better long term goal.
That sounds like a great idea for the long term, but what about the people that need a solution today? We have to make do with what we got until science advances.
Yes, yes, slowly cutting away at the non reneweable nerves, widening the gap to keep the connection working, becoming more cyborg as the time passes.
Sounds crazy, but for the reward it brings, is there a price too high?
