I think he's saying that eventually we will run out of economically viable to extract resources and we should start planning for that now. I'm not quite so sure because there are still tons of people living in awful conditions and they need a lot of this resource extraction to raise their standard of living. |

As cheaper sources are exhausted, the more expensive ones become viable. So we won't run out on the projected time horizon.
The main reason why US and Australian rare earth production has gone away is because Chinese sources are so much cheaper (aka no pollution or safety regs). No production, no exploration, and no development of rare earth sources.
As cheap production goes away, people again look for, build, and use other sources.
