Autism is in your brain. Your brain is configured the way it is because of your DNA. The only way you can cure yourself of autism IS by shooting yourself in the head and I do not recommend that.
You cannot will your autism away, or cure yourself of it by any method or effort. You may improve social skills with some practice, but they will always be impaired.
However, to answer the question, you are correct in your assessment that it would be a death of sorts to completely alter the configuration of your brain and eliminate half of the traits that formed your personality as you grew up.
Not only would it make you a different person, the person you are might find the new neural patterns painfully unfamiliar, confusing and overwhelming. After years of seeing the world out the window of an autistic head, the new view might be difficult to adjust to. You wouldn't have the benefit of years of childhood development to get used to the NT experience - who's to say that just being thrown into it, having never known it before, might not be decidedly unpleasant? It would surely be different, but would it be better?
Nah. I'm too old for adventures and risk-taking. My autistic brain may not be up to specs, but I'm used to it and I won't be driving this vehicle that much longer, anyway. Its gotten me this far, I can live with it another 20 or 30 years.
