You can trick Google's AI Overviews into explaining made-up idioms

Google's AI Overview feature shows flaws by interpreting nonsensical phrases as real idioms, attempting to explain made-up sayings instead of recognizing them as fake. This illustrates ongoing issues with AI hallucinations, where systems present false information as fact. The problem underscores the need for caution when using AI-generated content without verification, as demonstrated by a recent case of lawyers fined for using AI-fabricated legal citations.
