That works now because there are human made sources that the AI can find and summarize for you. But now there are no incentives at all for humans to write anything on the internet and if they do the content will be buried by hallucinated content someone else posted at a larger scale.

I had the similar experience to yours yesterday and it lead nowhere. Funnily enough I was also trying to configure a vpn on a router, google didn't return anything useful (besides a blog post clearly written by AI and with absolutely no information in it). Claude managed to give some interesting pointers, but its suggestions were not working and I also noticed that it started to hallucinate badly about ipv6 and gave me some suggestions that were just plain untrue. Claude Opus is smart, usually when it gets so convinced about something is after researching the internet and not just based on its training data. I wonder where it got so convinced about it. Maybe reading some other hallucinated blog post like the one I stumbled upon?
