I think the problem of discovery was solved, at least for the most part around 2003. A prompt would be tweakeable to yield the best result. After that commercial interference started to meddle with the results. Ever since, search results have become worse and worse. Nowadays an algorithm is cross referencing your prompt so that you get the most commercial result possible. AI could fix this, but for Nostr I think all we need is that brute force engine that Google developed 20 years ago.
