There is a quality about TBMs which vaguely reminds me of the feeling of getting a new LEGO set and building stuff. Imagine if we had cheap ways to build tunnels, no more traffic, no more congestion, roads and parking lots would only exist underground and cities would have more space for gardens, parks, buildings, and walkways. We have these things - Subways but its very expensive to build that system. Elon has an itch to solve this problem and I want this dream to succeed! While that's going on, please someone make a game out of building tunnels, it would be super cool!
