People need to experience a sense of competency and power as a part of feeling satisfaction with their lives. It is not the only route to satisfaction, but in my opinion it's one of the few roads to great satisfaction.

I agree with the sentiment that one can't be good at everything, and that there is a radically high-performance exemplar for anything, but for machines to dominate in almost every category of luxury endeavour -- yes I can see that as demoralizing. Even the useless things we spend our time on, we can be no good at that.
