I understand the desire to focus on the minutia of the tech. But the layperson's understanding of this situation is impossibly naive, and that "kid" you're envisioning? You do not understand how that brain operates. If you did, you would not be using language like "use cases".
I just reject the concept that we are already at the "nothing can be done to make it better" stage. Barely any effort has even been made.
I think of these beginning efforts in any science as the "Stone Age" part. As we can see, we're still trying to find a way to even define what we're doing.
