>>11395995Autism is a polygenic trait, probably a mixture of genetic load and developmental factors, recurrent mutations, many variables totally out of the control of any dedicated breeder. You could minimize its prevalence by banning processed food, industrial farming techniques, culling 90% of the european population. It would also involve hunting down and murdering most of the talented scientists, mathematicians and engineers that built and maintain modern technological systems but that is not as much of a logistical nightmare as trying to purge the gene pool on a massive scale.
