Writing in SEED Magazine, Mark Changizi expounds on his vision of human advancement in the centuries to come. He argues that the greatest progress will not come through changing our brains and bodies via genetic engineering or cyborg-like enhancement, but by developing technology that better accommodates the magnificently-designed brains and bodies that evolution has already given us:
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. All of these may well be part of the story of our future, but I’m not holding my breath.
There is, however, another avenue for human evolution, one mostly unappreciated in both science and fiction. It is this unheralded mechanism that will usher in the next stage of human, giving future people exquisite powers we do not currently possess, powers worthy of natural selection itself. And, importantly, it doesn’t require us to transform into cyborgs or bio-engineered lab rats. It merely relies on our natural bodies and brains functioning as they have for millions of years.
This mystery mechanism of human transformation is neuronal recycling, coined by neuroscientist Stanislas Dehaene, wherein the brain’s innate capabilities are harnessed for altogether novel functions.
