This solves the problem of pages full of ads and keywords and irrelevant content.
It doesn't solve the problem that's talked about in the article - there are other solutions, usually alternative search engines (kagi[0], or if more AI=more better, the kagi labs with contextual answers with sources[1]. Not sponsored, just like using them. Similar service offered by Hey.com, but I didn't try them much).
