The Immortal
At the dawn of this new technoscientific era, biohacking emerges as a controversial marvel, oscillating between the promise of a therapeutic revolution and the accusation of being a mere gimmick for tech enthusiasts craving biological transcendence. This practice, positioned at the crossroads of experimental biology and transhumanist exploration, disrupts classical medical paradigms and challenges the boundary between healing, enhancement, and human optimization. The question is no longer whether humans can be repaired, but whether they can be radically transformed — even transcended.

Between self-experimentation and cutting-edge science
Biohacking first takes shape in a multitude of practices, ranging from simple biometric tracking to subcutaneous chip implants, from nootropic consumption to DIY genetic editing. Behind this mosaic of approaches lies a deeply modern ambition: to regain control over biological mechanisms, even to preempt pathology by proactively intervening in the body.
It would be misguided to reduce biohacking to a few eccentrics injecting insulin for fun or embedding magnets in their fingertips. Figures from the highest ranks of biomedical research are now seriously exploring it. Advances in genetic sequencing, synthetic biology, and brain-computer interfaces lend scientific weight to practices that would have seemed fanciful barely a decade ago.

The body as a laboratory
What fundamentally distinguishes biohacking from traditional medicine is the subjectivation of experimentation. The individual becomes simultaneously subject, object, and testing ground. Radical autonomy, the ideological core of the biohacker, stands in stark contrast to the paternalistic model of conventional healthcare. This raises daunting ethical questions: how far can one go in experimenting on oneself? At what point does the pursuit of optimization become reckless risk-taking?
Some emblematic cases, such as Josiah Zayner or Brian Johnson, have shown that one can bypass the traditional healthcare system by applying sophisticated biological protocols on oneself. The body thus becomes a site of conquest, a field of continuous innovation, an interface to upgrade like a piece of software.

When technology extends life
Regenerative medicine, cellular cryopreservation, personalized supplements, gene therapy, and adaptive neurostimulation are no longer mere science fiction tropes. They now represent concrete research avenues in the most advanced R&D laboratories, often in close collaboration with biohacker communities.
In this regard, several devices are worth mentioning:
• Smart subcutaneous implants, capable of real-time monitoring of various physiological parameters and alerting users to imbalances before clinical symptoms appear.
• At-home neurofeedback headsets, allowing users to modulate certain brain waves for cognitive or meditative purposes.
• Longevity simulators, complex algorithms that cross biological and behavioral data to predict — and theoretically extend — active life expectancy.
These innovations fit into a forward-looking logic where health is no longer an end goal, but an ongoing optimization process. The body ceases to be a given; it becomes an upgradeable infrastructure.

Toward a new kind of medicine?
The shift from healing to enhancement raises a fundamental issue: the medicalization of normality. If everything can be improved — memory, sleep, mood, metabolism — then the distinction between treatment and performance becomes obsolete. This could eventually lead to an ontological redefinition of medicine itself.
Should biohacking then be considered heretical or the vanguard of an emerging medical paradigm? The answer, far from simple, will depend on our collective ability to regulate these practices, ground them in rigorous scientific methodology, and uphold human dignity and ethics.

Medicine has long been about treating the ill. But tomorrow, it may become the art of making the healthy better. A semantic shift with deep philosophical, social, and economic implications.
