Yum! Brands is rethinking its rollout of AI drive-thru technology, according to The Wall Street Journal. Customers, frustrated by the tech’s glitchy behavior and quick but wrong performance, have taken to trolling the AI by placing ridiculous orders (see: “can I get 18,000 water cups, please?”).

Taco Bell Chief Digital and Technology Officer Dane Mathews told the WSJ that the chain is now thinking carefully about how to use the tech — which it’s already put in more than 500 US restaurants — going forward.

We’re not expecting too big of a pullback: earlier this year, Taco Bell partnered with Nvidia and said it’s invested $1 billion into “digital and technology.”
