You remember the old internet. The one where a search for "how to fix a leaky faucet" returned a forum thread from 2004 where a retired plumber named Bob walked someone through the repair with hand-drawn diagrams. The one where you could find a niche community for almost any interest, populated by people who actually knew what they were talking about.

That internet is disappearing.

The Quiet Erosion of Search Quality

It's not dramatic. Google Search still works. You type a query, you get results. But the quality has been declining for years, and the decline is accelerating in 2026. The Walrus published a piece documenting what many of us have felt: search results are increasingly populated by AI-generated content designed to rank well, not to inform.

The economics are straightforward. Generating a passable "10 signs your [product] needs maintenance" article costs pennies with AI tools. It ranks for search terms. It captures ad revenue. The humans who used to write those articles — the actual plumbers, mechanics, and domain experts — can't compete with content produced at AI scale for near-zero marginal cost.

How AI-Generated Content Creates a Feedback Loop

Here's where it gets circular. AI models are trained on web content. As more of the web becomes AI-generated, new models train on increasingly synthetic data. The result is a kind of digital inbreeding — content that references other content that never had a human source in the first place.

This matters for two reasons.

First, accuracy degrades. An AI-written article about a technical topic might be 80% correct. A later AI summarizing that article gets to 70%. By the third generation, you've got plausible-sounding nonsense that's hard to distinguish from genuine expertise.

Second, the long tail of human knowledge — the things that only a few people knew and wrote about — stops being written down. The incentive structure of the web no longer rewards a domain expert spending two hours writing a detailed tutorial. So they don't. And that knowledge, once it's in someone's head and not on the web, may not survive retirement.

What's Being Lost

The Walrus piece focuses on Google Search, but the loss is broader.

• Procedural knowledge. The step-by-step guides written by people who actually did the thing.
• Institutional memory. Blog posts from 2008 about how a government agency implemented a system — now the people who wrote them are retired and the pages are gone.
• Community expertise. Forum threads where someone's specific, weird problem got solved by someone who'd seen it before.
• First-person accounts. The raw, unpolished writing of someone who was there.

For a professional audience — particularly in government IT and GovCon — this loss is tangible. The NIST guidance from 2019 that included that one paragraph about a specific control? It's still there on the official site. But the blog post from a practitioner explaining how they actually implemented it, with the gotchas and workarounds? That's been buried under AI-generated SEO content or the site went dark.

How to Find Real Information in 2026

The strategies for finding trustworthy information have changed. Here's what works:

1. Use primary sources directly. Go to nist.gov, cisa.gov, the actual regulation text. Skip the explainer articles.
2. Follow real humans. The people who consistently produce original, non-AI content are the ones worth subscribing to. If an article has the author's photo, bio, and byline, it's more likely to be human-written.
3. Check publication dates and site history. A site that started publishing in 2024 and has 10,000 articles is almost certainly AI-generated. A site that's been publishing since 2008 with a consistent author list? Probably real.
4. Use Web of Trust signals selectively. Some communities specifically flag AI-generated content. Hacker News, for example, has robust community moderation. r/experienceddevs on Reddit is another.
5. Pay for information. The ad-supported web rewards volume over quality. Publications that charge readers tend to invest more in original reporting and expert writing.

The Bottom Line

The internet is becoming a hall of mirrors — AI content reflecting other AI content in an infinite regress. The antidote is to become a more deliberate consumer of information and to value the sources that still produce original, human-generated knowledge.

Actionable takeaway: This week, audit your information sources. Identify three sources you trust because the author has real expertise, not just SEO rankings. Bookmark them. Subscribe to their newsletters. Those human-written sources are becoming more valuable as everything else gets noisier.
