I disagree. I think the point of the show is to illustrate how technology progresses. You could say one piece of it is about how we are reliant on it, and not in control of it, but I'd say overall, the show is optimistic about technology and celebrates innovation.
Edit: The Wikipedia article [0] does have a good summary, which I think makes us both right: There are really a collection of theses, none of which in my opinion dominate the show, except possibly the unplanned nature of technological evolution.
