A nuclear fusion reactor in China, dubbed the "artificial sun," has broken its own record to bring humanity one step closer to near-limitless clean energy.
I would think that using fusion or fission for synthesizing elements is going to still be less efficient (among all resources, not just energy) than using the newfound abundant/cheap energy to extract those preexisting elements from mixtures that exist on Earth.
Take neodymium, your example. That’s pretty abundant in the Earth’s crust. It’s just that it’s energy intensive to extract it from the mineral formations that naturally occur. At that point it’s still probably much cheaper, energy wise, to separate a bunch of minerals into their constituent elements, rather than try to synthesize atoms through fusion and fission.
