Greetings from 2050: what did we get right?

Fast forward to 2050. Imagine the materials now considered novel becoming ordinary in packaging, fashion, mobility, and everyday products, with recovery built into their design. Which technologies reached scale, and what had to change across investment, skills, and infrastructure to get there? And which decisions in the next two to five years would make that future credible? • Which materials could be ordinary by 2050, and which technologies will have reached scale? • What investment, skills and infrastructure are needed to get there? • Which steps in the next two to five years would make that future credible, and who must commit now?
