I also wanted a discussion of possible uses. I have no clue and I’m an engineer. And those are some rare elements, all of them I suspect. How much would this cost for useful electronics?

How much would this cost for useful electronics

The thing is there is almost no way to predict what it will be useful for. When something is this new and this different from available similar materials it could be useful in ways we just aren't thinking of because in the past they were uneconomical or impossible to engineer. As for cost, that is a chicken and egg thing. If no one has a use for it then it will be expensive. If it is super useful then someone will figure out how to mass produce it.
