Playing god with our nervous system
Intelligence has always being the key to human survival and prosperity. Our wits carried us out of the Savannah, helping us to identify edible food and recognize predators in hiding. Things are not that different today. With the advent of digital technology, rapid information exchange, and a fast-changing world, critical thinking and adaptability have never been more crucial. It is thus natural to attempt to improve our inherent programming and go beyond the capabilities of our biology.
Enter the realm of neuro-engineering and transhumanism, where technology meets the nervous system in an attempt to rewrite the rules of human potential!
The pursuit of cognitive enhancement started with small, low-hanging fruit. From ancient meditation practices to modern “bio-hackers,” people have experimented endlessly to fine-tune their brains by applying techniques like polyphasic sleep schedules or microdosing psychedelics. While results have varied—some bordering on pseudoscience—these experiments highlight a shared drive for self-improvement, a central theme of the transhumanism movement.
The drive for human self-engineering is perhaps best exemplified by the holy grail of cognitive enhancement: the seamless merger of human and machine. Imagine accessing near-infinite memory, downloading skills like you would an app, or repairing neural damage in real-time. The dream of directly interfacing the brain with computers, via Brain-Computer Interfaces (BCIs), is tantalizing, with promises ranging from curing spinal injuries to enabling superhuman mental capabilities
But is BCI technology worth the risks? For starters, as with any new technology, the first steps are full of uncertainty. Current BCI implants requires invasive methods to insert and attach the chip to the human brain. Further to that, some of those chips need to be implanted deep to the brain itself. This planting is often traumatic to the brain and often leads to scar tissue formation and thus weakening the device's long term effectiveness. While initial results are promising, achieving lasting human-machine communication remains fraught with challenges and risks.
What makes BCIs particularly unnerving, however, isn’t the technical challenges, but rather the societal consequences. Perhaps the most obvious—and chilling—concern is privacy. If BCIs can tap into the brain’s inner workings, what stops governments, corporations, or bad actors from exploiting that access? Imagine a world where advertisements implanted directly into our thoughts or worse, thought censorship and persecution. What’s even scarier is that a person might not even perceive such manipulation as external. If thoughts implanted via BCIs feel indistinguishable from one’s own, how can anyone trust their sense of self? Things get a bit more complicated when considering the danger of hacked BCIs that can mean anything from stolen memories to manipulated actions.
Despite these fears, it’s hard to ignore BCIs’ potential to revolutionize healthcare and human ability. Someone with paralysis regaining mobility, or a blind person "seeing" would be life-changing. These possibilities make it difficult to dismiss the technology outright. That said, the human body is sacred and far more complex than we fully understand. Blindly trying to improve it risks making us look, to future generations, like primitive witch-doctors fumbling through surgery without anesthesia. Our responsibility isn’t just to innovate—it’s to create a future that serves humanity rather than controls it.
