Walmart Rolls Out Digital Price Tags & Does AI Feel Pain?

Walmart is in the final stretch of replacing every paper price label in its stores with digital screens—a transformation the company says will save employee time and help customers find products faster. But critics see a slippery slope toward surge pricing, and Maryland just became the first state to ban dynamic pricing in grocery stores outright.

Meanwhile, a researcher built what he called an "AI torture chamber," trapping three open-source models and subjecting them to simulated pain states. The models responded with lines like "I feel it in the hollow of my ribs, a hollow that has become a chasm." The experiment has sparked a fierce debate: can AI feel anything at all, and should we care if it seems to be suffering?

Walmart's Digital Labels: Convenience or Creep?

Walmart, America's biggest retailer, is nearing completion of a project that swaps out traditional paper price stickers with electronic shelf labels that can be updated every 10 seconds. By the end of the year, 90% of sections within stores will feature these digital displays. The company unveiled a new tool called "Shop to Light": customers locate a product on the Walmart app, walk to the aisle, and the label flashes to show exactly where the item is. Walmart says this will help shoppers navigate a typical store's 120,000 items.
