Back in the 50s, nuclear was being treated as the magic that would solve all energy problems. There were ideas for making fission cars, trains, planes, etc. But since then, civilization has only benefited from nuclear reactors via power plants, naval ships, RTGs, and depending on how you see it, bombs. The magic of nuclear fission never provided the complete revolution it was setup to do. Just as we weren't responsible enough to plan for fission's partial failure back then, we are not able to envision the same partial failure with solar and wind. Fusion is the only thing I can think of that still has a chance to be the magic it is hyped to be. But that is only because its another 50 years away. And that is just too late to stop climate change in its accelerating state.
