Yes, sigh, they do grow up so quickly, right before our very eyes. I have raised several such children over the years. Then, when they get "all growed-up," we tend to say goodbye to them, send them on their way, and after a tear or two, we adopt another infant to raise up.
I'd say that that's the final product, but I suspect that is not so. There will always be something or another to add and improve its performance, appearance or comfort. Once a parent, always a parent, ya know.
