This chapter probes societal impact of micro/nano stuff, and the global transformations which are rapidly enveloping us. Microelectronics and nanotechnology, as they become increasingly pervasive in the global infrastructure of day-to-day existence, have the power to do much good for our world. And, alas, much harm. There are myriad issues swirling around the ensuing microelectronics and nanotechnology revolution. Time for a closer look and some open-ended thinking. Social media represent a new and fascinating intersection between micro/nanotechnology and global society. “Social media are computer-mediated tools that allow people to create, share or exchange information, ideas, and pictures/videos in virtual communities and networks.” Micro/nano is not necessarily a bright shade of green at first glance, but possibilities do exist for brightening this picture up and are receiving increasing attention.
