Asocial people on other side are not social, but they don't do any anti-social things - because that would mean that they have to socialize and that is opposite to being asocial.
Autistic people are not anti-survivalists, as by definition they have hightened fight-flight response, so they want to survive, however they have to really depend on society(humans by definition are social animals) to provide them survivable environment, so they could invent. Hardly any invention can happen, if there is no fertile ground, as being among morons requires different goals and skills to survive and adapt - with creativity.
Autistic people also are no anti-reproduction either - modern society is in general against reproduction, as there is overpopulation on this planet.
There are no problems to reproduce, if female is autistic, as she has much higher chances to find a partner and produce autistic offsprings, but it is more complicated for autistic males to find a partner and without a partner there is no reproduction even if males are pro-reproduction.
