"Autism is a superpower"

I see this type of message everywhere, people talking about the amazing talents that autistic people they've met have and calling it a superpower. They act like being autistic just comes with these amazing abilities.

I appreciate putting a positive light on autism rather than a negative one but it makes me feel like something is wrong with me. I don't have a superpower.

I'm slow, I'm bad at math, my memory is so bad that I fear I may have amnesia, I only ever did average at school and I've been learning the same language for 4 years yet I can't hold a real conversation. 

I'm not really intelligent or talented. The thing I'm best at is just being really interested in certain things (I consider it a good quality of mine) but it's nothing that would be considered a superpower.

Does anybody else feel this way? Is this type of thinking actually damaging to the image of autistic people?
