Well for starters, I feel blessed that I still enjoy going to work each day. The tools have changed over the years, but my primary motivation is still the creative "conversations" I have with my audiences during a performance. Sure, the automation has affected it, like I mentioned .... it's a bit of a disconnect, but not totally.
Bottom line: I will sing until I no longer can, or no one will come listen ... whichever comes first.

With regard to playing more acoustic instruments ... since I now have the automated accompaniment, and prerecorded tracks, I have the freedom to add more of myself, and add some versatility to the sound. When I customize a track at home, I relate to being a painter - creating a piece of art for sale. I do the research - practice the craft - choose the medium - assemble the pieces, and produce the piece for final appreciation ... again, and again, and again.
Then I get to play along, and add my spontaneous "sauce" to the stew!
