I'm 100% convinced this is a joke. The costs to do this are astronomical. I'll bet anyone $100 that within 6 months from today, this will be revealed to be a prank. Most likely a Nathan for You skit.
I would definitely be glad to work on a project like this!
Whether it will be successful is another question.
Especially when they buy a digging machine (still small compared to the ones I've seen near where I work), you can see it there: https://www.instagram.com/explore/tags/theboringcompany/
"Tunnel-boring is a notoriously expensive process. The Boring Company is looking to cut down costs by building a machine that can dig and place reinforcements in the wall at the same time, Musk said. Tunneling machines traditionally dig for half the time and then go back to add reinforcements, a longer and costlier process."
