Exactly. I hope to someday be part of the space settlements. 20 years puts me at my first retirement. The way it's looking the BFS will be used for exploring the entire solar system. Mars will be a second home for resupplies. I don't care what it takes I will be the equivalent of the guy shoveling coal. Whatever it takes. Who knows robots could take over everything (even fixing other robots) and the only job will be a party coordinator.
