It’s part of our ethos that technology can and should be a force for good. Our annual list of 35 innovators under 35 is a way of putting faces on that idea. In these profiles you’ll find people employing innovative methods to treat disease, to fight online harassment, and to create the next big battery breakthrough. You’ll find people using AI to better understand neurological disorders and to make cities more livable. This year's list shows that even in our hard, cynical world, there are still lots of smart people willing to dedicate their lives to the idea that technology can make a safer, fairer world.
