When you do your own web searches, you learn to trust certain signals over others. You learn which sources are trustworthy and which are suspicious. LLMs don’t do that, and they present every information to you as being equally valid.
I know within a second whether the search result I am looking at is obvious AI slop (search for almost any health condition, recipe, esoteric questions etc almost always have slop at the top of the result), but LLMs regularly source those sites as the basis for conclusions.
Sure and thats fair, there's probably many things that are good enough that I miss, but I'm talking about the most obvious possible websites being used regularly as sources in web search. Identifying poor sourcing or misinformation on the internet and what is a credible source has been a lifelong skill I've had to build from the early days of the web, and in the AI boom its only gotten more necessary to be able to not get taken by hucksters with billion dollar budgets.
