Elon Musk has really founded The Brick Store, which will sell bricks made from dirt unearthed from his Boring Company, public documents obtained by TechCrunch show. In September, the Tesla and SpaceX founder tweeted, seemingly sarcastically, that he would begin selling bricks as low as 10 cents each in about two months. The Boring Company's first tunnel, which runs under Los Angeles and is Musk's first attempt to alleviate traffic across the U.S., was completed on Friday. Musk then tweeted he was building a "watchtower" outside the tunnel's entrance made from dirt bricks, and documents suggest it also will be the site of Musk's first Brick Store. Musk is hiring a "knight" to guard the watchtower.
