I think is exactly right in principle and practically. The question is what domain knowledge you should improve on to maximize outcome: Will understanding the machine code be the thing that most likely translates to better outcomes? Will building the vector search the hard way be? Or will it be focusing on the thing that you do with the vector search?

At some point things will get hard, as long as the world is. You don't need to concern yourself with any technical layer for that to be true. The less we have to concern ourselves with technicalities, the further that points shifts towards the thing we actually care about.
