Gene Editing - How Far is Too Far?

What if you could erase a deadly disease - before a baby is even born?

What if we could cure cancer, prevent suffering, and rewrite life itself?

Would you do it? Should you?

Gene editing isn’t science fiction anymore - it’s real, and it’s happening. With tools like CRISPR, scientists can now cut and rewrite DNA. That means we could potentially cure deadly diseases like cystic fibrosis, sickle cell anaemia, and maybe even cancer.



The benefits

Let’s start with the obvious: gene editing offers life-changing possibilities.

Instead of managing symptoms, we could treat the root cause of many diseases by removing or repairing the faulty gene. In 2019, Victoria Gray became the first person in the U.S. to be treated for sickle cell disease using CRISPR—and the results were transformational. The results were life-changing. She went from constant pain to living a normal life.

And it doesn’t stop there. Imagine a world where no child is born with Huntington’s disease. Where parents no longer have to fear passing on deadly genes. If we could stop that pain, shouldn’t we?

In fact, I’d argue it’s not just a scientific responsibility - it’s a moral one. How can we justify ignoring that kind of progress? If we have the technology to stop people from suffering lifelong pain, shouldn’t we use it?

But where do we draw the line?

Here’s the dilemma: once we open the door to editing genes for medical reasons, it’s not hard to imagine people wanting more.

Once gene editing becomes common, it’s incredibly likely that people will want to use it for non-medical reasons. Once we start editing for health, how long until people start editing for height, intelligence, eye colour, even personality?

These aren’t just theories. The idea of “designer babies” might sound like science fiction, but it’s already happened. In 2018, a Chinese scientist claimed to create the first gene-edited babies. The world reacted with outrage and shock - not because it wasn’t possible, but because it was. What he did was technically advanced - but ethically irresponsible.




The risk of genetic privilege

Gene editing holds enormous power, but like any power, it comes with risk.
If only the wealthy can afford it, we could end up in a society where the rich aren’t just richer - they’re genetically stronger, smarter, and healthier. This kind of power is dangerous when it’s used without responsibility. Do we really want a future where only the rich can afford “better” babies? Where your DNA decides your place in society?

That’s not equality. That’s genetic privilege. That doesn’t sound like progress to me. That sounds like a nightmare. 


And what about consent?

The people whose genes are being edited -unborn babies - don’t get a choice.

What if the changes have unknown side effects? What if we accidentally cause more harm while trying to help? Our understanding of genetics is growing, but it’s still not perfect.

Gene editing isn’t just a high-tech experiment, it’s something that affects real lives, with permanent consequences.

My view

I believe gene editing is good, but only to a certain extent and for the right reasons.

We should absolutely use it to treat or prevent serious genetic diseases. But we need strong boundaries. The purpose should be healing, not enhancing. The goal should be compassion, not control.

That means:

  • Strict global regulations

  • Scientific transparency

  • Ethical oversight

  • A shared understanding of what lines should never be crossed

Otherwise, gene editing risks becoming a tool of inequality, not a solution to suffering.

The bigger picture

Of course, let’s not forget: our DNA may shape us, but it doesn’t define everything.

Our kindness, courage, creativity—those can’t be edited into existence. And if we try too hard to "perfect" ourselves genetically, we risk losing what makes us human in the first place.

In the end, gene editing gives us the power to rewrite life. But just because we can, doesn’t always mean that we should.

How AI Could Help Us Understand Hypermobile Ehlers-Danlos Syndrome

Image
One of the topics I’m most passionate about - and one that I’d like to share with you today - is Hypermobile Ehlers-Danlos Syndrome (h-EDS) and how AI tools might be able to revolutionise the research being done to understand it. What is h-EDS? Hypermobile Ehlers-Danlos Syndrome is a chronic, often invisible condition that weakens the body’s connective tissue -the biological "glue" that holds everything together. This means it can cause widespread pain, fatigue, and joint instability. But it can also affect organ tissue, skin, digestion, and even brain function. Despite its wideranging impact, there is no known genetic marker for h-EDS , and many people go years - sometimes decades - without a proper diagnosis. Because it’s invisible both to the eye and often to current scientific tools, h-EDS remains misunderstood and frequently misdiagnosed, even though it may affect as many as 1 in 500 people. There are 13 recognised types of Ehlers-Danlos Syndrome, and h-EDS is the o...

The Science Behind Hinduism: Ancient Indian Traditions, Texts and Thinkers

As a Hindu, this festive season - with celebrations like Ganesh Chaturthi, Navaratri, Dusshera and Diwali - has got me thinking about the deep connection between Hinduism and science. As I've started to learn more about Hindu traditions over the past few years, I've been deeply fascinated by how ancient Indian traditions weren't just spiritual, but often had strong scientific foundations. This festive season has inspired me to research more, and I thought that it would be the perfect time to explore how Hindu beliefs, practices, and discoveries have shaped scientific thought for thousands of years. In this post, I want to focus on 3 major parts of how Hinduism links with science - common Hindu rituals and traditions, Ancient Hindu texts and scriptures, and Hindu scholars whose discoveries are often forgotten. The Science in Everyday Traditions Many Hindu rituals that we see today actually have scientific reasoning behind them, so I wanted to research some of these ways of l...

What I Learnt From a Year of Being a STEM Ambassador

Image
Note: I was supposed to finish this post months ago, in July, but life got busy - sorry! I've finally finished...just know that I started writing in July (the end of the school year): As Year 10 has come to an end, I thought that it would be nice to do a post focusing on my experience as being a STEM Ambassador this year. At the start of the year, I signed up to be a STEM Ambassador - someone who helps lead and inspire younger students in science, technology, engineering and maths. I wanted to be a STEM Ambassador because I love science, and I wanted to share that love and enthusiasm with younger students so that they could also find a love for STEM. My main role? Running our school's STEM Club for year 7 and 8 students. At first, I thought it would be simple: plan a few fun experiments, show up to present, and everything else would run smoothly. I quickly learned that leading a club takes planning, a lot of patience, and a surprising number of late night text messages. Behind ...
