And then 30 years ago, maybe a little bit longer, there was this meaningful shift away from making these metals ourselves. We need to mine more copper in the next 15 years [music] than we have in all of human

There's a lot of worry about that, but there's no clear reaction by the western [music] mining companies in particular to actually go do it. >> We didn't just lose the capability, we actually fell meaningfully behind.
