My son, though he's yet to have a conclusive diagnosis, is very likely on the autism spectrum, as he's a bright kid but is absolutely "unable to deal with systems that do not have a lawful structure".
What's interesting is that my wife and I did the complete opposite of assertive mating. We're from the same hometown, with completely different backgrounds. We had different friends, have different educational levels, different ethnicities, different heights, different looks, different interests, and different perspectives. Genuinely two people from "opposite sides of the tracks" who meet just from randomly being in the same building. But the attraction and chemistry were instant and enduring.
(We also, interestingly, both have extremely high adaptability, almost to a fault. It's been a learning experience to create the type of routine our son expects.)
I know: it's just one data point. But I've watched the rising rates of autism with great personal perspective, and it's certainly a complex and multi-deminsional issue.
The other things to iterate are that autism certainly is a spectrum full of individual variation (almost to the point of not being a useful label), and autism isn't necessarily a detriment—it's a perspective and mode of being. If we could systematically avoid autism through a deeper understanding of the cause, I'm wondering what the unintended consequences would be. I know one thing: I would never change my son.
