The caveat being that this category exists within the current framework. The same could be said about "female hysteria", and pretty much all psychological conditions that have been left behind as symptoms of the zeitgeist.
At the same time, regardless of what you think the social conceptual juggernaut that is "Autism" is not going away overnight or even this decade, nor are the rest of DSM-V disorders. They serves a useful function, such as telling bosses to force their employees to attempt to work in a noisy workplace with flickering lights and off-gasses to fuck off. At this point the concept of autism has become tied up with peoples social identities, with the law, and with a whole lot of money on a massive scale and one doesn't simply unwind that all by going "This whole thing is dumb". One needs to start from the fundamentals, which is why was the social need for the concept of "Autism Spectrum Disorder" created in the first place and why was the concept promoted so readily by so many different interests?
Absolutely.
But until then, do you have a better alternative label or (armchair) diagnosis to use?
