These metals are used in LCD screens, mobile phones, computer chips, pharmaceuticals, fuel cells, etc... We are reaching the absolute limit of what we can manufacture using these metals.
Maybe recycling technologies are a good investment? Or will we discover new technologies like quantum computers as our elements go extinct?
