Nonsense. Artists use negative space all the time. You are approaching this from a purely mechanical stance which is, at best, flawed. You also seem to be assuming that a design is static, and never changes. The world is not a wrench, or a drill-press, something static and fixed. The world is a machine shop, and we are students set loose upon it. A great master has assembled a vast panapoly of creative tools, of raw goods and even instructions for their use. We have been given demonstrations for the proper use of these tools, and shown many ways in which they can be used.
This does not mean that a student will not pick up a file and turn it into a knife. This does not mean that a poorly-machined part will not break. This does not mean that improper care and use will not result in injury.
As humans, we have been given the entirety of the cosmos in which to explore, play, learn and improve. And yet everything we need is right here on our home planet, usually within easy walking distance. But instead of improving ourselves, building a utopia and exploring the stars, what do we do? We turn to greed, we turn to anger, we turn to lust. There is a marvel built in the middle of the Nevada desert, an oasis built on sand. It could be a testament to human thought, to perseverence. It could feed thousands on the water used in a day, it could power nations from the energy consumed, but what do we use it for? Debauchery.
When a neighbour’s child hits a baseball through your window, do you blame the one who made the bat and ball, perfect in their simplicity?
