For many years now, the field of gene editing and biotechnology has advanced at an astonishing speed, addressing progress that was initially only part of the realm of science fiction or our imagination. From curing genetic diseases to enhancing human capabilities, the potential benefits are incredible for our past selves. However, as with all powerful technologies, there are profound ethical dilemmas to confront. While the appeal of playing God with our genes is strong, we must be aware of the long-term consequences. For this reason, I am going to discuss three main reasons why we may encounter a not-so-pleasant surprise in the future.
Let's imagine a world in which the rich could literally buy better genes, because of course the reality would be that when this begins to happen only the wealthiest could afford to eliminate any potential genetic defect in their children, increasing their intelligence, their physical prowess, and even their attractiveness. Meanwhile, those who do not have the means win the genetic lottery and end up losing that effort to achieve "x" things. This is not a far-fetched scenario, but a plausible future if gene editing becomes commercialized. This scenario reflects concerns similar to those raised by Cornel West in "The American Evasion of Philosophy," where he critiques how societal structures can perpetuate inequalities and prevent genuine democratic engagement (West, 1993).
This would cause an unprecedented level of inequality when what we want to achieve in the future is to eradicate all the things that promote inequality, not increase it with one more situation. Because today we face a socioeconomic divide in which wealth determines access to quality education, healthcare, and opportunities. Now, let's add a genetic split to the mix. The rich and powerful could become a genetically enhanced elite, while the rest of society would remain "naturally" human, exacerbating the chasm between the haves and the have-nots. This new form of inequality could cause fragmentation of society, unrest, and even new forms of discrimination, and it is something that ultimately dehumanizes us: not everything has to be perfect nor can it be improved without any effort, it would be dividing society into an kind of "androids" that would be the "improved" humans and the rest of the humans that would be frustrated and trying to achieve that.
Mother Nature doesn't like to be manipulated and she is quite wise. Genetic engineering, despite all its promises, could have unintended consequences since we do not know the drawbacks and are not able to predict them. Even if we edit genes with the best intentions, the complexity of genetic interactions can inadvertently cause new problems. For example, editing a gene to increase muscle mass could have unforeseen effects on heart health, malformations, or completely unknown realities.
Moreover, genetic diversity is one of nature's best defenses against widespread disease. By homogenizing certain desirable traits, we may be setting ourselves up for catastrophic failures, which could wipe out humanity because we are all so genetically similar. A genetically uniform population could be more susceptible to diseases or environmental changes that we cannot predict. Think of the Irish potato famine or the destruction of crops by pests, but on a much more personal and human level. Once released into the gene pool, these changes are irreversible and could haunt humanity for generations.
Gene editing opens up a box of surprises on ethical issues. Today we talk about curing genetic diseases, a noble cause but not all of it would be for diseases as this industry would be commodified for other not-so-ethical things. So once you start down this path, it becomes increasingly difficult to draw the line between therapeutic and enhancement purposes. What begins as an effort to eliminate debilitating diseases could quickly devolve into cosmetic genetic modifications, designing babies with specific traits such as eye color, height, or even intelligence, which would set us back years of struggle over diversity. Henry David Thoreau's advocacy for individual conscience against societal pressures in "On the Duty of Civil Disobedience" reminds us that ethical considerations should guide technological advancements to avoid succumbing to the allure of superficial enhancements (Thoreau, 1849).
While I talk about this topic I can't help but think about eugenics, the practice, which is the practice of selective breeding of human beings to improve desired traits, sounds like it's a game in which you modify an avatar, but it is not a reality. History has shown us the horrors of eugenic policies, from forced sterilizations to the atrocities of the Nazi regime, and knowing the human race, I do not believe that everyone has learned from the mistakes of the past. Although modern gene editing is not the same, the underlying philosophy of "improving" the human race has dangerous echoes of these dark chapters of humanity and that are not so distant. The power of gene editing could easily be abused, leading to a dystopian future where purity and genetic enhancement would dictate one's value in society.
Gene editing and biotechnology hold incredible promise, but they come with ethical dilemmas that cannot be ignored. The possibility of greater inequality, unforeseen consequences, and the direct push for eugenics. As we stand on the edge of this new frontier, it is essential to proceed with caution, guided by a strong ethical framework that prioritizes the well-being of all humanity.
We must ask ourselves difficult questions: are we prepared to live in a world where genetic improvements create a new class of superhumans? Can we predict and manage the ecological and health impacts of our genetic manipulation? How do we avoid going from curing diseases to creating designer babies?
The answers are not simple, but we should always look more to nature, which is very wise, and not address things that are too big for us. The future of gene editing must be defined by careful reflection, international regulation, and a commitment to equality and human dignity. Only in this way can we take advantage of this powerful technology for the real improvement of humanity, without succumbing to its potential dangers, and putting our feet on the ground that we believe that we have everything under control and we are far from that perspective. Randomness exists for a reason, "imperfections too", it is great to advance but there are many advances that remain outside the reach of human capabilities.
