I don't think most people care if the information is true; they just want an answer. Google destroyed the value of search by encouraging and promoting SEO blog spam, the horrible ai summary that confidently tells you some lie can now be sold as an improvement over the awful thing they were selling, and the majority will eat it up. I have to assume the ad portion of the business will be folded into the AI results at some point. The results already suck, making them sponsored won't push people any further away.
