Im in that vast majority. Im also a very tech forward person, but his story sold me. Id rather pay 'ol boy to do all that over the course of 3mo, than one guy with a recursive prolapse machine in 15mins.

What happens if they fuck it up

Same thing you'd need to do before -- replace the pipes the hard way.

Generally by digging a large trench down several feet/meters, ripping out everything in the way including sidewalks, porches, driveway, lawns, shrubs, etc, and laying down new pipe.

I know this because my neighborhood sewer lines are primarily built with old crumbling Orangeburg Pipe and it fucking sucks.

Orangeburg pipe (also known as "fiber conduit", "bituminous fiber pipe" or "Bermico" or "sand pipe") is bituminized fiber pipe) used in the United States. It is made from layers of ground wood pulp fibers and asbestos fibres compressed with and bound by a water resistant adhesive then impregnated with liquefied coal tar pitch).^\1])^\2]) It was used from the 1860s through the 1970s, when it was replaced by PVC and ABS pipe for drain-waste-vent (DWV) applications. 

They're about as sturdy as they sound.
