These two young men are trying to make a go of it, in the way that makes sense to me--working with kids and families that have similar challenges, so that the ASD is an asset of sorts.

Personally I am skeptical that my ASD son would be well suited to other sorts of teaching. The social demands and complexity are way too high. Developing a relationship with a classroom and keeping it under control and productive is extremely difficult, even for very socially capable neurotypical people. Also schools are very chaotic environments and teaching requires great time management, executive function, and frustration tolerance--none of which are ASD strengths. Maybe if he were teaching at a high-end private school with smallish classes and kids who were very well-behaved and motivated for all sorts of reasons external to the classroom it would be OK. Or at the college level. But I think there's a reason why most of the successful people with ASD you hear about have made it in computer science or engineering--fields where you can work by yourself at your own pace, there's not a lot of social complexity, and the work product speaks for itself. (FWIW I know a few lawyers too, who did well in big firms or in the government). I'm inclined to nudge my kid in those sorts of directions, or toward the skilled trades like fixing old cars (e.g., John Elder Robison) or boats.
