Why are aspies always stereotyped as automatons, because we are less spontaneous?
Or maybe the "experts" studying autism just beleive we lack spontaneity because we are more reserved? Because we would rather save our speech for something profound instead of becoming talking heads

What if originality's definition is insufficient? Some NTs think that to be original one must act up, which is just childish. But for all their attention getting antics, these aforementioned folks have no original thoughts and actions. And then there are aspies who seem like nonentities who have creativity in a subtler form.
I find that once high school finishes, NTs act less the way I described, but every time I go into town, seeing these irritating adolescents drugging themselves into conformism makes me question the assumption that aspies cannot have novel thoughts.
Intellecually, Aspies can be very creative. Some of our greatest scientific genius may very well have been Aspies: Einstein, Dirac, Newton....
