:joy: How about a repo I can run that proves you know what you're talking about? :D Just put together examples and you won't have to throw around authority fallacies.

> if you add 2 vectors together nothing happens and its meaningless

In game dev you move a character in a 3D space by taking their current [x, y, z] vector and adding a different [x, y, z] to it. Even though left/right has nothing to do with up/down, because there are foundational concepts like increase/decrease in relation to a [0, 0, 0] origin, it still affects all the axes and gives you a valuable result.

Take that same basic idea and apply it to text-embedding-ada-002 with its 1536 dimensional embedding arrays, and you can similarly "navigate words" by doing similar math on different vectors. That's what is meant by the king - man = queen type concepts.

I think what the person before you meant about it not making sense is that it's strange that something like a dot product gives you similarity. To your point (I think) it only would assuming the vectors were scored in a meaningful way, of course if you did math on nonsense vectors you'd get nonsense results, but if they are modeled appropriately it should be a useful way to find nodes of certain qualities.
