Robotic Postal Clerk -- What's Next?

In Juneau, Alaska, Ruth Vincent, a manager at Mendenhall Valley Post Office, demonstrates one of the new automated postal centers. They allow customers to serve themselves.

Not shown: Clerks who will need to find new, less-robotic functions -- inside or outside the U.S. Postal Service.

Prediction: Within 10 to 20 years, more than half of all low-skill, repetitive U.S. jobs will go out of human hands.
