What makes you think you couldn't have made brownies without Google. Just go to your local library and find the first baking cookbook you can find. And there it is, a better recipe than Google without all the SEO blog spam.

To avoid my comment just being snarky, I agree that there's a difference between comparing Google to LLMs, and the library to Google... but still I hope you can acknowledge that LLMs can do a lot more than Google such as answering questions about recipe alterations or baking theory which a simple recipe website can't/won't.
