According to the story of the Voice, the Rave will look human but nothing about them will resemble us Homo sapiens. They will have an emotional intelligence that will change everything and render our oh-so logically logistical and strategic abilities useless. As if that isn't dramatic enough, our current Age of Planning will end around that time. The 400-year cycle that began in 1615, with the emergence of nation-states, the United States, the Industrial Revolution, will end in 2027. If you find the Rave story very hard to believe, anyone who has been in wars or at the very least been involved in media or financial services, to name just a few industries, knows first-hand the power of creative-destruction and how easily structures and concepts disappear.
But still all these stories from the Voice are just stories. I have no clue if any of this will really happen for real and, if it does, have no idea how it will all unfold. But they are stories with the powerful theme that nothing stays the same. They are powerful reminders that evolution and mutation are built into Nature. These stories remind me that advanced civilizations also existed before and also disappeared, gone with the wind. It's so easy to forget this with most of our first-world problems easily satiated with the click of a button.
Any educated person accepts Darwin's theories. You're viewed as a pretty backwards person if you don't acknowledge his theories on evolution. Yet, his theories are usually framed past-tense. In educated worlds, it's accepted as a scientific fact that we emerged out of apes or some other species, way-back-when. We're okay collectively dealing with evolution in the past-tense. We accept all that, past tense. But ask how will we evolve? Some of the most intellectually sophisticated people I've met scoff at even the possibility of a new species of man. It's like they can't even entertain such a possibility and yet they believe in evolutionary theory! I hear few scientists ever framing any of this in the future tense, or if they do, their views hardly make it to the evening news. Aside from Hollywood movie-makers, I hear very few people deliberating or speculating about our evolutionary track in the future, and in this absence reveals our inherent arrogance.
