I was reading about this last week.

https://www.bbc.com/future/article/20140314-the-worlds-scarcest-material

The issue isn't just running out of a particular material. The main issue is being able to replace those materials with other materials that work just as well and are in abundance.

Aluminum is one cheaper option to replace it but I don't think it's as conductive.
