McDonald's is ending its test of employing artificial intelligence chatbots at drive-thrus, raising questions over the fast food industry's rush to roll out the technology. The world's largest burger chain will remove automated AI-based order systems from over 100 locations around the US. The systems, which featured an AI voice responding to customer orders, had been tested as part of a deal between McDonald's and IBM that began in 2021. McDonald's gave no public reason for ending its test run, according to Restaurant Business, telling franchises that it would shut down the technology on 26 July. A spokesperson for McDonald's told the publication that it would decide its plans for automated orders by the end of the year, but stressed that "a voice-ordering solution for drive-thru will be part of our restaurants' future".
