@emilygorcenski that was a looong read, but worth it.
Just a question about the last paragraph and specifically “The earth contains only so many rare earth elements”: does it? AFAIK the naming of those is a misnomer, and they are in fact abundant, with large deposits all over the globe, just not yet commercially exploited. Certainly finite supply, but not scarce enough be an issue any time soon.
