It's a shift but it's a little worse. Checking/auditing search results is easier and more ingrained; even if many people don't do it, everyone has been hit by spam at some point, everyone knows it exists.

LLMs are the same thing but have an air of authority about them that a web search lacks, at least for now.

To me that's the opposite. Whatever an LLM gives me, I view with skepticism. If I google sth then I quickly get a sense of how much I can trust it and what the BS factor is. I can refine my view in either cae, but my a priori trust with an LLM is much lower.

Maybe we just need to work on training the general population to have a similar bias. (It will be harder than it sounds. Unbelievable amounts of capital are being bet on this not happening.)
