So, you then are staking your claim that Elon Musk has invested 8 figures of his own money in an area that he has no hope of improving upon the state of the art? And you are willing to predict right now that he has made no such substantial improvements to tunneling technology?

The industry is not stagnant. Riskier and more complicated tunnels are being built all the time. The craziest ones go under water to connect land masses.

No, because Elon hasn't invested his own money into this. He's investing money loaned to him by the bank against his SpaceX and Tesla stock.

I can't predict that he has not made any substantial or meaningful improvements to tunneling technology to date because (a) that's not a prediction, it's a statement of current affairs, and (b) it's already quite clear that he hasn't--and based on the Hawthorne tunnel, it appears that (c) Elon has actually regressed from current tunneling technology.

But yes, I am willing to predict that Boring Co will never make meaningful improvements to tunneling technology. Everything they've already suggested as innovative has already been done by existing players. BoringCo's road map for innovation for the next 10 years is literally them just playing catch up to everyone else.

Those two things are the same thing. A loan against a personal asset is the same thing as your own money.
