As a child, I expected to be driving in a flying car or vacationing in near-Earth orbit or on the moon by now.
What I didn't expect was the internet. Of all the technological developments that have changed the way modern society functions, perhaps none has presented such a disruptive challenge to society. It has changed everything about how we communicate with one another, shop, get entertainment, and receive our news—and of course the way science is carried out, to name just a few examples. Yet nowhere in mainstream science fiction was the internet imagined.
