LLMs read like ad copy even when they aren't ads. LLMs presumably trained on a ton of ad copy. A lot of ad copy is considered "public domain". Aren't the ads already injected and the real trick will be getting the advertisers to foot more of the bill?
I half believe Gemini already has an "AdSense billing model" in the works.
Only because the AI results haven't been infested with ads ... yet.
As soon as the VC lottery stops, the ads will get injected and the AI stuff will quickly go just as bad.
