Is it because the minimum wage hasn’t gone up much, giving employers little incentive to replace people with machines? Is it because the best minds of our generation are creating dating apps instead of useful labor-saving devices? Is it because the early stages of AI are so hit-and-miss that it does as much harm as good?
