In the same vein, I wouldn't oppose a cure for autism, despite my own diagnosis. Why go through the pain and suffering that comes with autism in a world of non-autists? I've seen more than enough of the lives of people with non-high functioning autism to realise the absolute living hell a cure like this could prevent.
I'm wary of the "cures" people have tried, most of them based on fake psychology or pseudoscience, but I have no reason to expect the authors of this paper to be in it to show how their kid is "normal", like most people looking for "cures" seem to be. I expect this article to be quoted many times in the terrible Facebook groups that will also recommend things like bleach enemas to desperate parents, but I also expect good developments from the real scientists trying to understand and perhaps cure (the worst cases of) autism.
