I think the conversation has become a bit too polarized. It's not really a choice between exact match keywords and topical authority—they work together. Exact match keywords are still useful for identifying search intent and shaping a page, but they shouldn't drive every sentence.
For example, if someone searches "best budget gaming laptop," I'd rather create a page that covers buying factors, comparisons, FAQs, and recommendations than obsess over repeating that exact phrase twenty times. The keyword provides direction, while the depth and relevance of the content are what make the page genuinely useful.
