Steve Bowbrick posts wondering if there’s a next generation of the “admirable, enlightened, imaginative old men” like Arthur C Clarke and Freeman Dyson. It is interesting that the generation of scientists that emerged post-World War II appeared to have no limits on how far their imagination would go. Dyson wanted to move planets around and make rings and spheres from them. Project Orion would have converted nuclear power from bugbear to boon. And there’s many more examples. Have we lost our imagination? Where’s the grandiose plans of today?
