To say the world is changing faster and faster is both A) an unabashed understatement, and B) a tiresome tirade that we see in too many lazy news commentaries (unlike this hard-working one, of course). We progeeks and profanes, being wired and technical, know the world is changing fast – some of us are responsible for it for that matter.
The world is changing frighteningly fast because of, let me state the obvious, technology. I imagine many a science fiction writer has watched the rate of change in the world and just thrown up their hands in frustration. Technology is one of the major drivers of change in the modern world.
