Getting any information on the Web requires battling dark-pattern tracking prompts, newsletter nags, and sifting through SEO fluff and content farms (that thanks to LLM, are only going to get worse).
I don't expect the ad-based Web improve, at least not until the tracking-based ad model collapses (either way bad news for Google). When the ads target users, not sites, then any site of any reputation can have profitable ads! This benefits quantity over quality and outrage-fuelled clickbait.
OTOH LLMs can give me a straight answer immediately. ChatGPT understands even terse queries, while Google ignores half of my keywords and substitutes the other half with irrelevant synonyms. With LLM I can ask clarifying questions without restarting my search. ChatGPT has issues and limitations, but I think it can improve.
