@Wildfire_desu Autism is classified as a developmental disorder that you have from birth (hence me using that term as we are discussing a cure for this "disease"). It shapes who you are at a base level, pushing this question into absurdity. But I will indulge your hypothetical situation.
How does this cure work? What form does it take? Gene manipulation while the child in question is still a fetus or fertilized egg/one of the stages before it takes recognizable form? Is that even a thing we should do? What about the environmental factors that likely play a role? We can't control those. So you want to "fix" a predisposition?
If that is too much, have alternatives:
"Just a pill" that you give to a young child? Or maybe even "only" something to drink for the baby/toddler? Something that
FUNDAMENTALLY ALTERS THE BRAIN STRUCTURE AND WHO THE CHILD IS? I am using children as the example here because the majority of diagnoses is early in life. Would you, as a parent, decide to make your child into someone else because they would have it "easier" in life?
But taking a step away from children and making it an option for adults with full cognitive capacity (mostly about things like depression and not those of us who are on the "low functioning" end of the spectrum). Would you take the option to not be yourself anymore? To let all the memories you have accumulated in your life be the ones of a different person? If you even keep them, since it's such a drastic change. Because that is what you are asking. And in case you couldn't already guess, my answer to these is No. I would
not take the cure.
I guess the absolute easiest is taking something akin to stimulants or antidepressants to fix whatever "imbalances" there are in the brain. Making it the safest for adults. We'd still have the same problem of being another person while on that medication. This isn't something like hallucinations or low moods. It's what makes you you. It's what shapes your experiences. It would be great if something that helps with sensory issues were found, decreasing the risk of meltdowns because of those. No, anti-epilepsy medication is not a sure way last I checked. But beyond that? I honestly like how my brain works. I have to use it in different ways to be as functional as a neurotypical person in our society, but I still like who I am. I am me and I am good the way I am. I already was someone else once. For most of my life. Would not recommend.
