I have a lot of confidence that Google will figure out a way to do it.

The same economic incentives that led to SEO slop are still there in my opinion.

More "content" equals more opportunity to integrate ads even if they are not woven into the AI response directly. It will be tuned to allow and all that changes is cutting out the website provider.

Google is incapable/unwilling to do anything beyond flooding the world with ads. They don't have a great track record of actually selling things to people for money.
