I'm asking a genuine question, out of ignorance, but - aren't the tech behind Theranos and Magic Leap the kind of thing you can easily patent and protect - whereas if someone discovers how to make practical fusion, they get a nobel prize and now the world knows how to do it? Fusion is undoubtedly critical to our future, but I think I can see why the investors don't think it's a profit machine in the same way as a new commercial gadget.

If something is patented it means you have to disclose how to do it. I dont see why you couldn't patent a fusion reactor. You can patent the underlying science, but the physical realization is patentable. If you manage to pull it off, you are probably super rich. However the risk of failing is much higher, and the time horizons are much longer than a silicon valley startup.
