Bogleheads (made up of investors who follow Bogle's indexing philosophy) recently had a thread about the decline in traffic to the forum, which some people attributed to AI. (https://www.bogleheads.org/forum/viewtopic.php?t=470287&star...)

It wasn't just "Why bother reading a thread if I can find the answer quickly using AI search/Gemini/Claude/ChatGPT?" There's also the Cloudflare effect, which stopped AI crawlers and bots from posting slop, but also led to some collateral damage ... BH content is less likely to be indexed, and some users will bounce from Cloudflare prompts.
