Could be. Could also be that LLM is to OpenAI what information retrieval is to Google. A lot is publicly known in the information retrieval space, but google still dominates.
That is good point. The original Google designs are public, those were papers that were published. Anybody could create a new 'google', its just about getting name recognition and users. Guess example is DuckDuckGo, or Bing, they throw money at advertising just to get users, but underlying search isn't the problem.
