Why do you think AI doesn’t exist? Or that there’s “no such thing as people ‘relying’ on it”? “AI” is commonly used to refer to LLMs right now. Within the context of a gizmodo article summarizing a study on the subject, “AI” does exist. A lack of precision doesn’t mean it’s not descriptive of a real thing.

Also, I don’t personally know anyone who “relies” on generative AI, but I don’t see why it couldn’t happen.
