@__h2__ My dream for Mars is to see canyons covered with a fish tank for a roof (to grow algae and provide radiation shielding) with adobe houses on the canyon walls and tunnels bored deeper to expand the usable space and offer even more radiation shielding. I'm picturing something like Ceres Station from The Expanse. I know that's literally sci-fi, but it's more fun to daydream than to be a pessimist.
