How we chose to use it and what happens to those in the precariat. The precariat - meaning here those who get displaced from work when innovation happens. Why is it reasonable that some people get socially disadvantaged when an innovation happens that makes their work much more efficient? Not saying that that always happens but this disadvantage itself, and not the innovation, I would say is a reasonable reason for being a luddite.
