If you’re in the US, you might see a new shaded section at the top of your Google Search results with a summary answering your inquiry, along with links for more information. That section, generated by Google’s generative AI technology, used to appear only if you’ve opted into the Search Generative Experience(SGE) in the Search Labs platform. Now, according to Search Engine Land, Google has started adding the experience on a “subset of queries, on a small percentage of search traffic in the US.” And that is why you could be getting Google’s experimental AI-generated section even if you haven’t switched it on.
Brisket coffee rub is fairly common. I only know one guy who uses a coffee injection because it’s not common, although other injections are pretty common for brisket.
I have no idea why it went off on that particular tangent. I guess whatever barbecue data it was trained on had a lot of injection advice along with the coffee rubs.
