The bulk of the article is about a kind of pseudo-scraper for populating links and references whilst writing a blog post or article. But the broader conversation piece here is whether linking in an age of LLM-driven content is still needed, to which I and the author agree: it is. Now more than ever. Not because linking serves any specific purpose in terms of differentiating humans from machines (LLMs are just as capable of generating linked Markdown etc.), but because, as Crash Lime writes, doing so should help build a "Web of Trust"; a web of verified information, which is known to be at least relevant. That is something LLMs (and, indeed, search engines) stand less hope of pulling off... for now.
On the ending of an Age (and just a really fun way of describing the situation):
Perhaps we’re at the end of the old-web, now a corner relegated to hobbyists, as all text ever written is absorbed in a single differentiable scream.
On the concept of a "web of trust":
Remember that you are not just linking, but building a Web of Trust. Links need to be a signal that cuts through the noise, not vice-versa.
