"Can speculation about the future of technology serve as a measuring stick for what we create today? That’s the idea behind Envisioning Technology's massive infographic (PDF), which maps the future of emerging technologies on a loose timeline between now and 2040.
"On it you’ll find predictions about everything from artificial intelligence and robotics to geoengineering and energy. Mouse over the entries for blurbs describing them and links to more information; you won’t find much more than a Wikipedia page explanation, but that’s plenty helpful for the uninitiated."
