A spring is a spring is a spring, just as a nail is a nail is a nail, so the analogy
Your analogy is flawed based on basic metallurgy alone. If a "...spring is a spring..." then why have all manner of industries come up with validity testing, Quality Controls, Random Sampling to maintain a higher standard of product and improve on what we once had. If I were to follow your analogy then I'd still be driving a model T, using iron nails on my roof, drinking water from the river... Sorry, that kind of thinking did not get us to the moon...
