Human beings seems to have this desire for greater and greater realism.
My film history professor said this last night during our first lecture. In discussion about the Lumiere brother's mini "actualities", he noted how early theater-going audiences became quickly unsatisfied with current image technology. Though the latest machine called the Cinématographe was then producing clear quality moving images, once viewers had seen enough, they wanted more. Movement wasn't enough. Color wasn't enough. Sound wasn't enough. Size wasn't enough. Effects weren't enough.
If you think hard on that sentence above, you'll find yourself becoming frustrated with the nature of humanity. We crave more and more and that's sad. Someday, nearing the end of our lifetimes, we will probably see something close to holography being used to connect across continents instead of Skyping on bulky and impersonal computer screen.
We want to see reality in media and technology. The clearer things are, the better we understand them. We want to be swept up in a world that is not our own but is easily relatable as to be able to adapt. We want our minds to be blown by possibility. We desire greater and greater realism. Through film and technology especially, this generation is starting change what it means to be human and how humans should and will interact socially in the near future.
