Does anyone else think that really the ultimate goal of the boring company is to create the first long term habitable buildings on mars? In order to protect the early setlers from solar radiation they need to go down about 100 meters below the surface of the planet. Not only that but in the companies published FAQ it states that they also plan to use all that dug up dirt to make bricks for the tunnel with plenty left over for resale. On mars those bricks would come in real handy in constructing buildings and other city structures. Far easier to make your construction materials onsite than to fly everything there on a rocket. Thoughts?
