If you were a miner, that tool that helps you dig faster would put you out of a job, because now they only need half the miners to do the same amount of work.

If you were an artist, a lot of the point is the material things, or the process. Why on earth use oil paint than instead of Photoshop or other digital tools? Why do people use paper at all? It's so inefficient. But art really is personal and inefficient most of the time.
