As for 28 years ... 10 results that's more recent. Google used to offer more results per page until they worked out the more people clicked ... wasted time ... the more ad revenue it made for them.
Otherwise, yes AI can't be relied on making a good summary. I used to till 2015 do research to manually confirm data for various people who wanted to be sure. Back then too many sites and places didn't have the most accurate information being second hand information or the summary was dumbed down and some of the nuance was lost.
If you want a better search engine, Kagi ( https://kagi.com ) is a good place to start. Yes, it's a paid product -- once you outgrow their free plan, which offers 100 searches -- but they've got a lot of quality-of-life features & they're focused on user privacy. I've been using it exclusively for 2.5 years already -- I haven't touched Google, DuckDuckGo, Ecosia, or any others -- and I have no regrets paying for it.
The only downside I can think of regarding Kagi is that it's US-based. But until another company is able to do as good a job while operating outside of a Five Eyes country ( https://en.wikipedia.org/wiki/Five_Eyes ), I'll be sticking with Kagi.
