Some of that turn is physical plant. Kitchens, especially, are built to serve human forms, where tech solutions to food prep would rather be stand-alone boxes. It's a far harder problem to make a robot that uses a restaurant's existing grills, ovens, and deep fryers than it is to make a box that turns out perfect french fries. It's a riskier proposal for a restaurant to replace its fry station, where a human can make fries, onion rings, egg rolls, or whatever new fad hits tiktok, with a fries-and-rings-only box with less than 10 years commercial proof. Generative AI, for all its faults, is just code that runs on a computer you already have, or maybe in a cloud service with zero physical footprint. Relative to replacing your barista with a vending machine, trying ChatGPT for a quarter or two is practically zero risk.
