You have plenty of literature that can act as ground truth. This is not a terribly hard problem to solve, it just requires actually focusing on it. Which so far simply hasn’t been done. ChatGPT is just the first “look, this can generate text”. It was never meant to do anything useful by itself or stick to the truth. That all still has to be developed. ChatGPT simply demonstrates that LLM can process natural language really well. It’s the first step in this, not the last.
Brave has their own index as well. And if you want Google results in not-enshittified, try Kagi.
That aside, the biggest frustrating in the search space is the complete lack of innovation. All those search engines and their alternatives do the same thing and look the same. There haven’t been new features or new sources of information in about a decade. The whole space has been extremely stagnant.
The only new thing we got recently was ChatGPT, but as search engine replacement it really doesn’t cut it right now, it can enter Wikipedia-style general knowledge question ok’ish, but completely falls apart on anything even mildly obscure (e.g. summaries of lesser known movies are completely wrong). I hope that something good comes from all the AI development, but BingChat so far is a really lack luster and ham-fisted attempt at integrating search with AI, often performing much worse than plain ChatGPT instead of better.
