To my way of thinking, there are two distinct/separable propositions here.
1] Will autistic people, by virtue of being 'loners', have a higher likelihood of surviving high mortality events such as epidemics/pandemics (and therefore of 'keeping the species alive' by re-populating in the wake of such events)?
2] Is the autism phenomenon
Nature's work, or is it more like a fortuitous accident/windfall event created by something UN-natural - e.g., increasing exposure to various toxins which are themselves products of our technological civilization (which might well be a one-off event)?
Some research on slime molds suggests it is advantageous to have some 'loners' in your population:
Evolution selects for 'loners' that hang back from collective behavior—at least in slime molds
