if you cant' see it, it's not there.
What ever "it" is, if you can't see "it", I'd agree "it" doesn't matter to you; but that doesn't mean "it" isn't there - again depending on what "it" is. Anyhow this is beside the point. You posed a questionable dichotomy between people who measure and people who create. I was simply saying that numerous very creative people use numbers and measurements for crafting what they create, while of course others may not. The reality of creative processes is highly varied and nuanced.
