I've read through the post and this reads more of a memory lane of Google, rather than getting into the statement "Now, for the first time, its cultural relevance is in question."

There are a few links scattered about on relatively minor topics , but nothing substantial showing that it's in question. Either that's clickbait, which I'm now starting to associate with the verge, or it's far too early days to tell.

Like other comments here my impression is not the same as the post. And the slivers of reasoning given are weak at best.
