How big a startup is required to reach scale of billions of answers, with no tracking nor ads

The open Web is (long) gone and Google results have been getting worse for years now (e.g. just try 'is Google in decline' on Google). YottaAnswers (https://yottaanswers.com), the project I have been working on shows how to build a smart AI Q&A system capable of billions of answers with no tracking nor ads. The scale of the system is not that far off from Google, with orders of magnitude fewer resources and the system being based on vector spaces as opposed to keywords and indexing that are a legacy technology.
