Ask HN: Will AI obliterate small search services? (e.g. DDG, Brave search)

While Microsoft and Google press ahead developing AI in their search engines, what will happen to the search engines like DuckDuckGo (DDG) or Brave search, or others? These small, independent, privacy-friendly search services are tiny compared to the tech giants. Will AI obliterate small, independent search services? (Or see their usage drop further?) Can AI be incroporated in other search services?
