Some search engine results are crap, yes. But even the worse search engine (minus AI overviews or whatever) gives you a setup where: (1) each piece of information has an actual source, (2) you know who the source is, and (3) you can make decisions about which information to trust accordingly. If a popular search engine puts a sketchy company’s blog at the top of the SERP, you can actually see that and choose to look father down for something more reliable. Also, if your current search engine keeps failing you, try a different one! There are many options out there that you might find more helpful than today’s Google or Bing or DuckDuckGo.
Good luck with things, truly. I think you’re going to get hurt eventually if you use LLMs for medical advice, and I genuinely don’t want that for you or anyone. Hopefully this conversation has at least made you a little more skeptical about using LLMs in certain ways.
