Thanks Jokerine for your thought.
Taking Ainan seriously is easy: you just have to listen to what he is saying. Indeed, he presents anyone who meets him with a curious duality: his appearance is that of a young boy, but when he speaks the meaning of his words is that of an adult scientist thinking creatively with rather more imagination and flexibility than is usual in an adult.
Once you get past his childish appearance, you can see an "adult" mind within, in terms of his scientific thinking. I am used to it - but this dichotomy of appearance and mind comes as a surprise to anyone who speaks with him for the first time. Recently, his new Principal called me very excitedly after her first conversation with my "amazing son", as she referred to him.
So, if I can find an environment for him where people judge each other on the merit of their thoughts, rather than their appearance, he will be fine. The only question is: is there such a place?
