I too am retired, but at the end of my career, I was doing mostly tech support by phone. Not in the phone firewall, or reading cheat sheets to callers, but at senior level, where either the cheat sheets didn't help, or, more likely, where the juniors had picked the wrong one. That meant that I actually had to know how to fix things on my own rather than hoping that I could guess which canned response would work, and an AI probably wouldn't be any help, because if it could fix things, the junior wouldn't have needed my help.
