That's an unfounded assumption. There's lots of work that goes undone because it's cost prohibitive. Technology in this case increased overall value because it allowed Lynne to do something that no one was doing before.
Because technology gave us levarage, and lowered the cost. Lynne's pay is ultimately set by the market. Lower her pay and see if she leaves to make more somewhere else.
Maybe it would be doable at a lower salary. Let's pay Lynne half as much as yesterday for this new job.
