The Feynman vision unifies physics and computing in an effort to understand physical processes. If realized the payoff would be life-changing for humans. Examples abound and are discussed later in this book, but for now consider just one example that could change the prospects for all of humanity: if humans could better understand the basis of a physical process like photosynthesis (one that naturally takes advantage of quantum effects to capture energy efficiently in ways humans have not been able to replicate), we might find ways to harness energy from the Sun far beyond the capacity of existing solar cells. The same insights might allow us to store that energy for when we need it, and then use that energy to grow more food and ultimately feed more people. The Feynman vision is our lodestar for quantum technologies, as it is the most compelling one to support more life and at a higher standard of living.
