Author is a human :). Performance and semantic accuracy are both important. The point about pre-filtering _youre still searching millions of vectors_ is important because once you apply a filter you can no longer use your vector index. And doing a full scan on millions of vectors is quite expensive

Maybe i was just too narrow focused on the comparison itself and did not get that point. Anyways, as a whole was a valuable read, along with hn comments made me reconsider current implementations details in my projects
