Not everybody with autism is as high functioning as you are though. Lets put it this way, if autism is supposed to be the next step in evolution, then why is it still classified as a disability?
That's because it still continues to be for many people, a disability. I know several people with autism where it impacts their ability to drive and live independently. My 33 year old overweight co-worker who's only working a $10 part time internship despite the fact that he's college educated. Or the nearly 40 year old woman who's on SSI who I used to go to school with. Or the neckbeard looking former roommate who continues to be a part time janitor. Or the man with classic autism who can't even have a normal conversation with someone. And these are just some of the stories, not all of them.
For all of these people, their autism definitely impacted their life in a negative way. They may not admit to it, but if all of these people were neurotypical instead of autistic, they probably wouldn't be in the shoes they are now. Some of them probably would have gone to college and gotten a good job, gotten married and had a kid or two, and have a more "normal" life.
I'm not saying everyone with autism is doomed to a life of underemployment and dating woes, but for many people with autism, that turns into a realistic possibility. The vast majority of us aren't the Albert Einstein's, Elon Musk's, or Sheldon Cooper's of the world; there are real struggles with being on the spectrum and it impacts people greater than others.
