I've been characterizing it to others as the difference between hand-carving a post for a bed frame vs. letting a CNC mill do it. The artistry-labor is lost, and time-savings are realized. In the process, the meditation of the artist, the labor and blood, sweat, and tears are all lost.
It isn't 'bad', but it has this dulling effect on my mind. There's something about being involved at a deep level that is satisfying and uplifting to my mind. When I cede that to a machine, I have lost that satisfaction.
Some years ago, I noticed this same issue just looking at typing vs. hand-writing things. I _think_ very differently on paper than I do typing at a terminal. My mind is slow and methodical with a pen, as if I actually have time to think. At a keyboard, I am less patient, more prone to typing before I think.
