Elon Musk's Boring Machine Completes the First Section of An LA Tunnel (theverge.com) 139
New submitter simkel shares a report from The Verge: Serial entrepreneur Elon Musk says his ambitious tunnel-boring endeavor, aptly named The Boring Company, has officially started digging underneath Los Angeles. Musk announced the news on Twitter, where he said "Godot," the Samuel Beckett-inspired name of the company's tunnel boring machine, had completed the the first segment of a tunnel in the Southern California metropolis. Prior to today, it was unclear how long it would take Musk to convince the city to allow him to move the experimental effort beyond the SpaceX parking lot in Hawthorne. We don't have details on what Musk hammered out with the city of LA. But he did tweet earlier this month about a meeting with L.A Mayor Eric Garcetti to lay the groundwork for the necessary permits and regulatory approvals he'd need to start digging with Godot, which weighs about 1,200 tons and runs about 400 feet long. Musk said last month that the first tunnel would run from LAX to Culver City, Santa Monica, Westwood, and Sherman Oaks, with later tunnels covering more of the greater LA area. Now, it looks like the LAX to Culver City route appears underway.

SpaceX has had unprofitable periods and profitable periods. General consensus is that it's probably running around the break even point on average, but it's doing that while plumbing a large amount of R&D money into reusable rocket technologies, developing them and currently trying to drive the refurb window down to days. That may not meet your definition of "profitable", but if nothing else, it's employing a lot of people, helping local economies, advancing the state of the art in aerospace, and has directly driven launch costs down while causing competitors to find ways to make access to space cheaper too. That's already a win, even if they go bust tomorrow, which is unlikely.
There's a similar situation for Tesla [fool.com], plumbing a huge amount of money into a battery factory and generally investing for the long haul, not for immediate profit.
Unlike many businessmen, Musk is not in it for the money. He's in it to change the world in ways he believe are for the better. Will it all work out? Probably some will, some won't (I'm not sold on the viability of the Boring idea), and there are problems with his approaches (e.g, running employees to the bone) but it's still a damn sight more impressive than "schlub at Starbucks". He's done more for the world than you will do if you had a hundred lifetimes to do it in.

How is it safe to be underground when the earth starts shaking? Turns out underground structures are safe because they move with the soil, while structures above ground sway back and forth.
Imagine a plate of fruit-filled gelatin dessert. Tunnels are like the pieces of fruit at the base of the gelatin, while above-ground structures are like the fruit toward the top. If you shake the plate, the movement becomes more exaggerated as it flows up from the base of the gelatin. In an earthquake, this translates to tunnel movement measured in inches, while the movement above ground might be measured in feet.

There is nothing stronger than a tube in the ground. Far more secure during a 12.0 earthquake than any overpass. Your far more likely to die from being trampled in an earthquake than from a tunnel collapse. We are not talking about mine shafts but rather oversized concrete tubes. A tube could split in half and move 3 inches and still be perfectly fine and usable.
The bigger issue is structures on the surface and ground stability during and after the evacuation. If they are drilling in rock or underneath rock then it should be much of an effect. But I can see Musk digging tunnels underneath other tunnels.

- automated, continuous tunnel lining, to reduce downtime for the boring machine
- speeding up both boring and lining
