Elon Musk's plan is great, but I really hope that it won't affect the families living above ground once they start drilling down there, or another natural disaster happens. And I'm sure he's got money to burn, but I hope that he has enough billions to help the families that will be affected because of this futuristic technology.
Yeah, and you know what the worst thing about that is? It's that those affected families will probably accept Musk's dirty money because they have nothing. If Elon Musk wrote them a check with an impressive amount for the damage his project caused to their homes and livelihood, they will probably take it, even if they will have a hard time looking for a place to relocate in that costs less or within the given check's price range. Meanwhile, Elon Musk and his followers will continue ruining other families' lives for his futuristic technology.
