Well, if you don't get the joke in the title gif/images, then perhaps this will help (yes, it is an old movie but still very funny!). I the "Airplane" movie is still one of my favs!
So, vectors and what the heck they are all about. Well, of late, vector databases have been getting a lot of visibility as well as established database vendors (Postgress etc.) adding vector database functionality.
Vectors appear in many AI/programming contexts, but one realm is text embeddings used in a lot of AI models to represent words/phrases etc. as arrays of numbers that can be used to find similar things.
Two great videos below will explain vectors, text embeddings and vector databases a lot better than myself!
A great 30 min intro to text embeddings
A quick dip into the world of vector databases (yes, the Fireship guy again!)
