AI is making surge pricing a lot more common. “The only thing holding physical stores back from using dynamic pricing is the time-consuming task of updating price stickers — but tech is changing that. Walmart is bringing digital price tags into 500 of its stores, and French supermarket chain Carrefour has been using electronic shelf labels since 2014.” Surge pricing is here to stay. (One hopes that variable pricing will also mean certain goods and services will be cheaper at times.)
