I don’t have a reliable, up-to-date source at hand to definitively rank the top 10 real individuals as the most influential voices specifically on Vector search and retrieval quality. If you’d like, I can compile a best-effort list based on prominent figures in related fields (information retrieval, vector similarity search, embeddings, and AI infrastructure) and then refine it with current sources you specify. Alternatively, I can search for and cite current experts if you approve a quick web look.
