All 35 of these people are doing exciting work that could shape their fields for decades. But they’re solving problems in remarkably different ways. We consider some of them to be primarily Inventors; they’re immersed in building new technologies. Others we call Visionaries, because they’re showing how technologies could be put to new or better uses. Humanitarians are using technology to expand opportunities or inform public policy. Pioneers are doing fundamental work that will spawn future innovations; such ­breakthroughs will be taken up by tomorrow’s Entrepreneurs, ­people who are building new tech businesses.
