Mark Changizi, author of the upcoming book Harnessed: How Language and Music Mimicked Nature and Transformed Man, writes:
Where are we humans going, as a species? If science fiction is any guide, we will genetically evolve like in X-Men, become genetically engineered as in Gattaca, or become cybernetically enhanced like General Grievous in Star Wars. […]
Simply put, none of these scenarios are plausible for the immediate future. […]
We have already been transformed via harnessing beyond what we once were. We’re already Human 2.0, not the Human 1.0, or Homo sapiens, that natural selection made us. We Human 2.0’s have, among many powers, three that are central to who we take ourselves to be today: writing, speech, and music (the latter perhaps being the pinnacle of the arts). Yet these three capabilities, despite having all the hallmarks of design, were not a result of natural selection, nor were they the result of genetic engineering or cybernetic enhancement to our brains. Instead, and as I argue in both The Vision Revolution and my forthcoming Harnessed, these are powers we acquired by virtue of harnessing, or neuronal recycling.
In this transition from Human 1.0 to 2.0, we didn’t directly do the harnessing. Rather, it was an emergent, evolutionary property of our behavior, our nascent culture, that bent and shaped writing to be right for our visual system, speech just so for our auditory system, and music a match for our auditory and evocative mechanisms. […]
The road to Human 3.0 and beyond will, I believe, be largely due to ever more instances of this kind of harnessing. And although we cannot easily anticipate the new powers we will thereby gain, we should not underestimate the potential magnitude of the possible changes. After all, the change from Human 1.0 to 2.0 is nothing short of universe-rattling: It transformed a clever ape into a world-ruling technological philosopher.
Seed: THE NEXT GIANT LEAP IN HUMAN EVOLUTION MAY NOT COME FROM NEW FIELDS LIKE GENETIC ENGINEERING OR ARTIFICIAL INTELLIGENCE, BUT RATHER FROM APPRECIATING OUR ANCIENT BRAINS
