I tried using the auto-router in KiCAD on my last <simple hobbyist> design and realized that it had been removed from KiCAD.
There was some external package that could do it, but at that point “screw it, I can route this board faster than reading the docs on how to deal with the autorouter” took over, especially since I couldn’t be sure anything I learned for this project would still apply for my next project if KiCAD later re-added an autorouter.
So ... while I can't say anything about PCB design in industry ... I can say that I tend to use a auto-router for my small DIY audio projects and it has never really failed me.
And ... if auto-routers are not used in the industry ... maybe that is something somebody on here should "disrupt" ... computers have become just too powerful not to be combative in solving some constraint path finding problems.
