For about the last year and a half Google results have been less useful - so yes it's fairly recent(-ish).
Especially for tech stuff. We used to have Reddit to turn to as an alternative, but now that's not working.
https://www.dexerto.com/tech/google-admits-reddit-blackout-tanked-search-results-2191128/ - e.g. the Senior VP for searching in Google even admits that Google is not as good anymore, somewhat as a result of the Reddit issue but that was only propping up the problem that Google itself caused, by allowing SEO (Search Engine Optimization) to rank predatory webpages over real ones with actual content.
I don't know of any solutions to this. I was thinking to search on places individually - like SlackOverflow, but now that company too is having a strike from its volunteer workforce just like Reddit. Google, Twitter, Reddit, Slackoverflow, they all are having MAJOR issues right now, as a result of not wanting to pay their workers and get something for nothing.
So they are turning to AI to solve their problems. AI doesn't understand shit, and in its current form simply parrots the answers that it gets elsewhere, without proper context or anything, or even acknowledging at all where the original content came from. So now as the sources of true content are drying up, and the well having been poisoned, true information is suddenly much more rare and precious than it ever was, yet harder to find than ever before as it is mixed in with all the sewage of people vomiting up their emotions, and actively upvoting things like snarky answers or memes rather than "real" ones.
The information age seems to be over, and in this Late Stage Capitalism we are now entering a new era, whatever it's called (maybe disinformation age?).
