So many misconceptions in this writeup.
Here's one: even if it were genetic, there could be triggering environmental factors that trigger the onset of autism (I'm just giving a hypothetical example, not making a claim here).

  For example, 45% reduction in symptoms from fecal transplant: <a href="https://news.ycombinator.com/item?id=48158494">https://news.ycombinator.com/item?id=48158494
  > Prior to the study, 83% of participants had "severe" autism. Two years later, only 17% were rated as severe, 39% as mild or moderate, and incredibly, 44% were below the cut-off for mild ASD.
  Incredible! Sure, there could be a genetic component to what flourishes, or ever seeded, in one's microflora, but there's definitely some external complexities involved here.

    It just says they behaved better, that's not recovering from severe autism at all... They didn't magically acquire language from a fecal transplant. Misleading
