autist also suffer from hyper sensitivity to various stimuli, sound, smell, light, textures, etc. sometimes is so intense they get a physical reaction, certain smells cause vomiting, sound triggers fight or flight, etc. Keep in mind this can be triggered by everyday stimuli, with the smell example it could be something like a perfume or food item that might not be considered smelly by normies.
autists special interests can also cause autists to forget everyday task and needs, such as sleep, eating, hygiene or time. Been awake for days just reading, did not eat or sleep for 2 days just reading.
Autism also cause a higher need for routine, any errors or obstacles breaking this routine can cause autistic meltdowns. These meltdowns if they manifest in a more external manner could cost you your job or in worst case scenario land you jail time.
Autism is more than social retardation, and i wrote just a fraction of issues this condition causes. Keep in mind i left out comorbidities something that is common among autistic individuals, there is a lot and is quite common for autists to have several.
One final thing im not saying ADHD does not cause issues or less issues than autism, my point being both condition causes issues and difficulty for the one who suffers from it, but what they suffer from and how they suffer differ.
