What's the Fresh New Non Earth Host?

In ten thousand years, we may be able to convert planetary matter into giant space structures. I just love imagining am future habitations that are built about as haphazardly as cities are built on earth. Or howr literally mindsdpet ye am, you know, dysons spheres, where you're like living on the inside of sphere that's a surrounding a sun. Those are lig and great idea, great use of matter and all kinds of stuff we can't even imagine.
