Actively programming? At age 12. We didn't have a computer at home so I had to use the one at school and wrote my programs on paper by hand them typed them into the computer at lunch time as fast as I could to see if it would work! I was so happy to finally get a computer but it was kind of fun to look forward to lunch time.
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.
