I think the only thing that can tell us whether or not every database can be a vector database is time. We have seen this with Time Series databases that they are their own unique type of database, and I believe this will be the same with Vector Databases.

I can help you put right now. You don't even need a database to have a "vector database". FAISS is an in-memory "vector database" that runs on the data that you happen to have. So: if you data is stored in a .txt file, load it into memory, index it with FAISS... bam a vector database from a data file.
Can we take X arbitrary "real" database and implement KNN search on top of 1000 indexed columns, I'm sure it is possible - but I'm also pretty sure most databases will die under the pressure (source: I've asked some of my favorite DBAs if I could do this and they said "no")
