Other technologies on the list could reduce greenhouse gas emissions by electrifying air travel and enabling sunlight to directly power the production of industrial chemicals. With “spatial” computing, the digital and physical worlds will be integrated in ways that go beyond the feats of virtual reality. These and the other emerging technologies have been singled out by an international steering group of experts. To win the nod, the technologies must have the potential to spur progress in societies and economies by outperforming established ways of doing things. The steering group met (virtually) to whittle down the candidates and then closely evaluate the front-runners before making the final decisions.
