It's all hypothetical anyway, what's your deal? Are you saying the totally hypothetical life changing cure is something to be impressed by so much, that the real suffering caused by those pursuing it is to be ignored? Ignoring the real suffering for some hypothetical deus ex machina is very cowardly, and if my hypothetical sacrifice reminded you of that, that's fine.
"If Elon Musk gave a shit about anything than profit, and knew his ass from his elbow, and this tech was feasible, and you were paralyzed, would you do it?"
He doesn't, he doesn't, it may not be, and I'm not, so the question is moot. But it's very scientific to ask, and a great way to navigate such society impacting questions, thanks!
