dcblogs writes: Walmart this week said it will offer a job to any honorably discharged veteran in his or her first 12 months off active duty. It also said it will buy an additional $50 billion in U.S. products over the next 10 years. Something else Walmart is doing is buying 10,000 automated checkout systems. The chain now has self-checkout systems installed in 1,800 stores; this new purchase will allow the chain to expand self-checkout to 2,500 of its approximately 4,000 stores. The company says the automated systems will not result in job cutbacks or reduced hours for employees. But others aren’t so sure. Automated self-checkout "does eliminate jobs, there's not much question about that. The question is how many?" said Frank Levy, an MIT professor emeritus of urban economics. Producing the automated systems will create jobs, but Levy said that the net overall effect may be job loss. "We should be thinking about it as a big problem," he said.
"The fundamental principle of science, the definition almost, is this: the
sole test of the validity of any idea is experiment."
