Elon mistakenly suspected that boring machines are like rockets. Press the button, they do the same thing every time, and you get to orbit or have more underground volume. Assuming you launch in nice weather, the atmosphere is the same every time. Orbit is certainly the same every time. Rocks and dirt are ironically more complicated to the point of there not being an automatable one-size-fits-all solution. The industry was also not restricted by the federal government as a weapons technology or inaccessible due to a high cost of entry like rockets were. Several companies around the world have had the motivation to innovate, and have.
