Wow, well as the father of a autistic boy, and having thought about God’s purpose in this thing, I have some ideas...but the point the person making the video is getting across is valid.
Early on, after the diagnosis I saw signs of mental powers, and abstract thinking, hindered by communication skills that were possibly set in place for a purpose. These are receding or non existent now to my eye. Dormant until needed?
As a primary point, to go along with the video my son would never hurt anyone, unlike certain people running for high office.
I think we will all be surprised one day when we know the truth behind autism.
