  • We find that technology can be useful and clearly necessary, but that it is not worth the expense of our youth’s creativity, intelligence, activeness, and innocence.By 2013 there will be 1.2 million industrial robots working worldwide — that's one robot for every 5,000 people, according to Marshall Brain, founder of How Stuff Works and author of Robotic Nation. Robots are currently analyzing documents, filling prescriptions, and handling other tasks that were once exclusively done by humans. http://www.nbcnews.com/id/42183592/ns/business-careers/t/nine-jobs-humans-may-lose-robots/#.UgpD2X-NCQU (13.08.2013)
