I don't look at asteroids as dangers and dumb rocks. They are made out of things that could be useful. Some day we will be mining those flying mountains and building independent cities out of them, perhaps converting some to interstellar ships. The things we might do!

Yep, they'd be very useful.
Not if they collide with Earth, though.
