It is very easy to believe that Autism is not a disability and that due to savant syndrome maybe those with Autism are a bit superior. Unfortunately it's just not true. There are a lucky few who can hide it well and are high functioning enough to eke out somewhat of a normal life. There is a large majority of very disabled people who are never going to have a normal life. In between there are a number of people with Autism, especially females, who have somewhat reduced symptoms with age not because they grew out of it but because they learned how to mask their symptoms.
On a personal note my youngest brother is a typical low functioning Autistic. He talks in echolalic speech, is unaware of external stimuli such as traffic, has a low IQ, and will just leave the room if there are too many people. He is a low level savant who can recognize some words without being trained. And he enjoys obsessively adding up numbers. As an adult he lives in an institution and requires daily care. Not exactly what one would think of as a superior form of neurodiversity or even better adapted to the environment of technology.
By contrast I am extremely high functioning with a life that would be the envy of other Autistics. My IQ is uncertain with scores on a childhood test of 162 but in college a score of only 120. I have the stereotypical engineering degree. Additionally I am a savant who was able to read at age 3 or 4 by observing word shapes and processing those shapes, their colors, and movements. Daniel Tammet has a very similar ability with numbers. I have a wife and a job as well. On the surface I seem like a savant superhero. A real success story.
The problem is my life is filled with disability that is only overcome by very hard work and the ability to trick others into the facade of normality. I have mild dyspraxia and my movements are clumsy with very poor proprioception. I have agraphia due to my mind operating on swirling, moving shapes that makes my handwriting nearly illegible. I have dyscalculia due to my number line having certain numbers that exist out of body and get tangled up. To compensate for difficulty with numbers I found equations with no numbers in them and let my text processing handle the logic. Computer programs. My social life has been abysmal. As a child the other kids hated me and I was very unpopular. For years I pondered the question "what did I do wrong?". There is an instinct of behavior that NTs have. Compliance with these behaviors is not optional and non-compliance is punished violently. I had to learn from books what these expectations were as a teenager. Through experimentation with various mimicry and things from books I was able to make people like me. I learned to force myself to maintain eye contact for longer periods of time too. Unfortunately the longer I hold eye contact the closer people get to me. That's a little terrifying. Another social problem is a difficulty understanding third person. When someone else is talking negatively about a person who is neither me nor them I cannot help but to think they are talking about me. That has led to more than a few fights or arguments. Visual overloads are common too. As someone who lives in a world of moving colors and shapes things like solid green grass or the colors and words in the supermarket can be overwhelming. I tend to wear sunglasses outside the house to tone down the signals. Tricking other people into thinking I am normal or masking is part of everyday life. In my early childhood my parents would tell me to stop rocking so I learned to suppress the rocking. When children in kindergarten saw me hand flap they laughed so I learned to move that into a facial tic or eye blink. Instead of having outbursts of meltdown I internalize that into a shutdown and become temporarily mute. The end result of all these coping mechanisms has been enormous stress and anxiety throughout my life. I take anti-anxiety medication and self medicate by overeating. Eventually it will kill me.
The point is my entire life has been learning how to move autistic behaviors into NT behaviors like a trained dog. That's not a cure. That's not a superman. Neither is it some evolutionary technology adaptation to the upcoming singularity. I am a person with multiple disabilities that are crippling. Period. Neurodiversity is not superior. It's a curse. Anything else is the delusion of mythology.
