A number of industries require holes in the ground. Plumbing (for water in, out), electricity, telecom, and so on. People have to come and dig. It's sweaty, sweaty work. And the pay kind of sucks.
However, telepresence gets better every day. A robotic digger sends telemetry to an office, where, on a computer, or shovel-like interface, a worker can operate the machine from air conditioned comfort. It still operates about as fast as before, but the working day is longer and more comfortable, so the low pay isn't quite so objectionable.
The machine is probably even the same shape, just with a computer and antennae instead of a human-cabin....
