You'd be insane for any regular person to try this anytime soon. Anyone who has practiced medicine for any significant period of time has seen very routine procedures have catastrophic complications... Even 99% success rate we see all of the 1% complications. The brain is not forgiving.
I have had so many patients with debilitating strokes/ALS/MS/TBI etc who can't pick up the remote to change the channel and effectively lay there all day fully dependent- for them stuff like this could be game changing.
