Amazon's top operations executive says they're saving less-tedious jobs for the humans who work as "pickers" and "stowers" for the robots. "It's a new item each time," Mr. Clark said. "You're finding something, you're inspecting things, you're engaging your mind in a way that I think is important." The Times reports that the robots "also cut down on the walking required of workers, making Amazon pickers more efficient and less tired. The robots also allow Amazon to pack shelves together like cars in rush-hour traffic, because they no longer need aisle space for humans, [meaning] more inventory under one roof, which means better selection for customers."
"When Amazon installed the robots, some people who had stacked bins before took courses at the company to become robot operators. Many others moved to receiving stations, where they manually sort big boxes of merchandise into bins. No people were laid off when the robots were installed, and Amazon found new roles for the displaced workers, Clark said... The question going forward is: What happens when the future generations of robots arrive?"
