Why are we so fascinated with randomness? If you disagree, let's look at advertisements. Advertisers look at current trends to see how they can market a product, spending a lot of money on research. If we look to most commercials nowadays they are the most arbitrary things ever (e.g. Old Spice, Keystone, etc.) Why is this?
I posit that whatever scientific theory of the time is most prominent, a society/culture will act accordingly. When we thought the Earth was the center of the Universe, we thought we were the sole purpose of creation. That changed when the heliocentric model put the sun in the center. Even more so when we saw how big the Universe is. Science humbled a planet.
Currently, science states that we live in a disconnected, random, and reductionist Universe headed toward entropy - total chaos. If that's so, then society will act accordingly. But what if we shifted toward believing everything is interconnected, interdependent, and headed toward "centropy" (a state of balanced flux)?
Euclidean geometry provides answers for 2D events. Great, but the Universe isn't flat. Everything has a 3rd dimension. To say the Universe is flat means all of the things within are flat. Last time I checked, I'm not.
Similarly, current scientific models of reality are based upon the assumption that closed and finite systems exist. Of course the laws derived from these systems will work because they're derived from the closed or finite system themselves! The issue them comes when we ask, "where do we ever see a closed or finite system in Nature?" Nature is always connected, always infinite, always open, and always interdependent.
So if art reflects the times, what does that say about us now? It says we live believing everything is random and has no purpose. However if we took a moment to actually be in Nature again, to observe the details of Nature, we'd see the opposite. Now imagine what sort of art and technology we'd develop them. Think of how we'd interact with each other if we were aware of our true connected and interdependent Nature.
