the earth is old though, i'd think that the sun will have expanded and made the planet uninhabitable before all the crust is recycled. i've heard there's only 500million years left, assuming we don't destroy it before then.
I heard 100 million, so. Anyway, it seems we might Earth’s last chance to seed other planets and stars.
We gotta start working seriously on fusion torch drives and fully self contained space habitats that can operate without any external materials for thousands of years. That and power plants that can last that long.
