That’s how we will overcome the challenges we face: by unleashing the power of all of us for all of us. Not just for those of us who are fortunate, but for everybody. That means creating not just a quicker way to deliver takeout downtown but also a system that distributes excess produce to communities where too many kids go to bed hungry. Not just inventing a service that fills your car with gas but also creating cars that don’t need fossil fuels at all. Not just making our social networks more fun for sharing memes but also harnessing their power to counter terrorist ideologies and online hate speech.
