Anyway this article is about AI replacing web search, not "killing the web" which I would take as it somehow deleting or overwriting content on existing webpages. Or generating so much spam as to make the web unusable for the average person.
Large sites that can't exist without "traffic" already killed the web a long time ago. A paywall is the proper solution, not ads in content and content in ads. That means you will have lower traffic, it doesn't mean you are being killed. It just means you stopped assaulting passersby who are linked to your site.
