Our entire family is on the Autism spectrum. We have an advantage in that we don't have to be taught to be alone - we are not lonely just because we are alone, if anything the rest of the world forces us to be with huge numbers of people as a regular thing and then we need more alone time. Tech however has made a big difference in our community, as it enables non-speaking Autistics, or other people with disabilities that complicate speech, to communicate more conveniently, and as such has somewhat eliminated the assumption that Autistics are all stupid. The Internet has a huge community of "our people" and we know each other well, online.
Our family seems to be unusual, based on your apparent definition of normal use of technology. When I worked for a nonprofit back in the 90s, my boss offered me a cell phone. I turned him down flat, because I wanted to have my family time BE family time, At the time I had 4 kids and was pregnant. We generally do have family breakfast and supper with our 15 year old, the last child left at home.
To this day, we take a cell phone along only when needed for contact with a care provider, when needed for safety, or when we will be away for extended (like, days to weeks) time, and important calls might come through. And we have a *gasp* land line, which we treat much as my partner Rex's grandmother did in the 60s - "A telephone is a convergence. We are at supper now. It is not convenient to answer now."
