Yet the pace of innovation is accelerating, as is the focus, owing in part to the climate agenda and government support, in part to decisions by investors, in the part to the collaboration of different kinds of companies and innovators, and in part to the convergence of technologies and capabilities—from digital to new materials to artificial intelligence and machine learning to business models and more.
