A. I believe that there are most likely multiple factors at play in causing autism and that the specific combination is likely not the same for everyone, and if that's the case, it's at least unlikely that there will ever be any one "cure" that works for everybody.
B. I know there are ethical questions about children and those who are otherwise unable to make the decision to get a "cure" or to express their feelings about it having it forced on them.
C. I really don't feel like debating terminology right now.
But, saying all that...
There are people like me for whom autism is absolutely, unquestionably a disability with little or no benefit coming from it, and I would personally be ecstatic if some sort of "cure" was an option.
