Think this is the second time I've seen laser digging methods in the last month. Anyone know what route The Boring Company was/is going down for digging?

They drill straight down for heat and only use the laser/microwave/whatever once they hit the bedrock layer. Boring conpany generally isn't going that deep and is going horizontal so possibly these techs don't apply.
Yeah, I would say using a high-energy contraption to vaporize rock (and any other stuff that might be in the way) sometimes just a few meters away from utility lines, other tunnels, people's basements etc. is generally not recommended. Plus, for geothermal drillings, the holes are much smaller than for transportation tunnels.
Gyrotron, not laser, as per article.

(A gyrotron doesn't seem to be a class of laser, any more than a light bulb is...)
