What metaphors are used in Y2K by Arthur L. Kopit?

The author admits to using the title, Y2K, metaphorically, "hoping it will suggest the deeper, more profound Year 2000 Problem: our potential loss of personal and political freedom through technology. We depend on these machines now for almost everything and are therefore vulnerable in ways we have never been. Our view of what is real and what is not, and what is inviolable and what is not, is going to have to change. So will the way we see ourselves. In a very short time, you'll be able to find out pretty much anything you want to know about anyone."
