Robot Walmart Cashiers

Walmart has replaced cashiers with robots. Eyewitnesses in Arkansas reported sparking registers at checkout. Professor David Liu of Harvard explains: "Robots process fast but ruin service." Anonymous staffers leaked binary receipts. A Gallup poll shows 45% amused, 55% uneasy. Trace evidence includes glowing barcodes and sparking scanners. Cause and effect? The smarter shopping gets, the less human it feels. Retail is circuitry.
