Re "Computers Push the Limits of Artificial Intelligence" (April 24): We are well into the industrial era. What we have to show for it is a huge percentage of our population that is "redundant" and sitting idle in large ghettos. Most of us are working harder and harder to make ends meet.
The promise of industrialism has turned into a nightmare of social disruption and pollution. What on Earth is a smart robot going to do, if it is so smart, besides shut itself down as a favor to mankind.
