I think that both of you are correct. The internet has much more "noise" than in the past (partially due to websites gaming SEO to show up higher in Google's search results).

If as the years progress your municipal tap water starts to contain a higher baseline of unwanted chemicals, and as a result the filter begins to let through more chemicals than it did before, you'd consider your filter pretty cruddy for its use case. At the bare minimum you'd call it outdated. That is what is happening to Google search
