But where are we at now? Have we already invented the alternatives so it doesn't matter how we use what's left? Or are we waiting for future people to consume those resources to invent some as-yet-not-invented alternatives? How will they even know they're on the path to inventing those alternatives and decide to consume the remaining resources for that goal instead of uselessly saving them forever like a hoarder?

Turns out we didn't use up fossil fuels before we invented at least some alternatives, so lucky us. But that's not because previous generations restricted their economic development to altruistically save some for us, which is what modern save-the-resources people want.
