Ok, but people won't use it just for recipes. If it's successful and common place google will monetize it.

The beginning could just be "see this related product or service." Which won't mess with the content. Perhaps that's fine.

I'd argue though that any summarizing tool inherently has a bias. It must choose to ignore certain details and make decisions about what to highlight.

As we understand LLM's more and the stuff that summarizes folks controlling them will be able to make those decisions and the money and power behind that will absolutely abuse it.

That's not even considering the effects this would have on journalism and writing in general if most of it gets summarized.
