I have been heard such stories even in early '90.
I remember when Eagle IIc appeared. "High end ....perfect... it will clean all the terrains....already cleaned sites...no finds...end of days! ..."
No. It will not happen.
Always will be new customers and new sites to "clean".
Machines are getting old. Must be replaced with new ones. New models will always catch attention, all over again and again.
It is never ending story.
Situation now is even better. Newer machines are mostly uPc oriented, smt, high density pcb's . Once that machine mutilate, who's gonna service it?
Once components getting old and jitters - time to replace whole machine, time to buy new model.
Never ending story.
Last decade mostly roman coins and relics were target. Empty sites? Time to switch to older period! We need better machines? Yes!
Same story with personal computers, many times in the past some people predicted "end of days" for that technology. Wrong!
Metal detectors will live more longer.
Business will survive.
Look cell phones technology today, almost every person have at least one device. Enough? No more customers? I don't think so.
Keep the faith dear friend!
