Does the overuse of technology worsen autism?

Hi doctor,

In my school, there are a couple of autistic children. There is one kid with whom I was relatively close. He was never really able to speak fluently obviously, but could still talk and have basic conversation. He could say 'Hi', his name, and similar simple phrases. But over the years, as our school has started using more technology, he can do all his talking through an app on his digital device. Now he appears to be far more isolated and anxious than he used to be. He cannot talk now and seems to be getting worse now that there is no assistance in teaching him things. I am just wondering if this is because his autism is getting worse. It just breaks my heart to watch this once bright young kid who used to play with everybody now turn into a kid who sits with his eyes glued to a digital device all day with headphones. Do you think I should bring it to the school board that we need to put more effort into trying to keep these kids able to care for themselves? I honestly do not know what to do, but it has bothered me so much that I have decided to further my education in psychology and childhood development.

Thank you.
