I think it is wonderful you can be there. I wish you could teach where my son is starting middle school this fall. Middle school is tough. Period. I can only imagine it is nearly like h*ll to a kid on the spectrum. I am not looking forward to it, but I can tell you I'd be much more at ease if I knew one of his teachers could understand him the way only another spectrumite can.
You know, I don't think it is nearly fast enough, but times are changing. When my daughter was first diagnosed, the mention of the word "autism" made caregivers, summer camps, and schools slightly...well...terrified. This year when I enrolled my daughter into a "mainstream" summer camp and I told the director that she was autistic, it elicited about as much of a response as saying she has a food allergy. Instead of alarm, it was more like "Not a problem. Are there certain things we should avoid? What should we do if she is getting overloaded?"
I say this to state that I am hopeful that kids today will have it better than even you did (you appear significantly younger than me in your picture).
It can only benefit him to have you as a role model. Lucky kid!
