Gary V Godot

TBC, The Boring Company
AT&T, American Tubes and Tunnels
Tunnels R Us

Whatever Elon Musk names this "hobby", I don't really care. If you need me to explain the context for this, you really need to start following Elon Musk more closely.... That being said, here the context is:
Elon Musk was stuck in LA traffic one day, and thought "You know what could alleviate congestion? Tunnels!" From here, he purchased a tunnel boring machine, named it Godot after the play "Waiting for Godot", and also went to a pet store and purchased a snail, which he named Gary. The purpose was to show that Gary, a notoriously slow snail, is currently still faster than the machines we bore tunnels with. The eventual goal of TBC appears to be to dig hyperloops throughout the united states, starting with LAX-SFO and BWI-JFK, but no one is sure what Musk is thinking until he does it.
