Over the last year, its become palpable.
Google has such utility in this regard that in some cases, a hallucinating lie-machine offers better answer than an index of what information is available on the internet.
This issue with with Googles failure to respond to the deluge of SEO driven content in their searches. They can do better. They've chosen to not do so.
It can only index stuff that's on the Web. Stuff on the Web is, contrary to what is popularly asserted, only a tiny fraction of all human knowledge.
I think people are forgetting how bad search was before Google. Google drove Web directories to extinction. Remember Yahoo!? Back in that era, if I were looking for something as simple as the University of Michigan, I clicked and drilled down through a Yahoo directory. The obvious search query would have been useless. Google changed all that.
I view Google as the yellow pages. It works well for that. Is it an oracle of knowledge? Of course not. How could I possibly expect to find knowledge on a place where there is no reward for making it available? People producing knowledge don't work for free.
I've tried ChatGPT and it's no better. It serves up stuff that is flat-out wrong.
For example, just the other day I was searching for one string that I knew was part of a common code repository. To my surprise google couldn't find anything at all. Yandex on the other hand found the repository immediately and linked to github.
Other common issue with google is the difficulty of finding stuff like forum posts related to the search query. Sure, you could append "reddit" to the query, but there are still plenty of traditional forum sites and some of them have decades worth of discussion. I Never see those sites pop up on a typical google search unless I specifically look for them. Again, with yandex, my experience is much better, it is not uncommon to see posts from forums to be on the first page of results.
