I wouldn't be surprised if a 2x or 3x more efficient boring machine is the ultimate product of this and it makes future infrastructure projects much cheaper as a result.

I wouldn't be surprised that for such a niche industry he couldn't make it 20x more efficient. I also wouldn't be surprised if he could only increase efficiency marginally because its a hard problem. But these niche problems often have huge potentials for efficiency gain.
