Rewriting the Book of Life: One Synthetic Chapter at a Time

This isn’t something I would normally write about, yet whilst seeking information about my own chromosomal abnormality, I had the urge to seek more information about bio-synthethic humans. From there, this article flowed out of me:

Ever dreamed of building a human genome from scratch — not editing, but writing it, start to finish? Well, science just took its first solid stride into that wild possibility. UK researchers have launched the Synthetic Human Genome project (SynHG), backed by a cool £10 million from the Wellcome Trust.

Their aim? To digitally design and build an entire human chromosome in the lab. Not in some Frankenstein fantasy, but with meticulous precision, serious bioethics, and long-term benefit in mind. Yet let’s be honest — it sounds like something straight out of Gattaca, Westworld, or the dusty pages of a Philip K. Dick novella.

But here’s the twist: This isn’t about playing anyone’s god. It’s about better understanding the one we inherited.

By creating synthetic DNA — not editing existing strands, but writing the whole sequence from scratch — scientists hope to unlock new insights into how our genetic code works, misfires, and mutates. That could mean big things: virus-resistant organs, safer cell therapies, and disease-proof tissues crafted to order.

Now here’s where it gets personal — and a bit sci-fi tragic.

Say this tech makes it to the finish line, and say it works. If there’s a waiting list for the first volunteers to receive a fully synthetic immune system, a cellular refresh, or hell, even a full body reboot — you’d find my name etched somewhere near the top. Because the idea of living longer, better, unburdened by the crumbling bits of biology that betray us with age — it’s tempting. Too tempting.

But I’ll admit, there’s a curve-ball in the dream: love.
I love being in love.
The deep kind.
The hold-hands-at-sunset kind.
But longevity — or worse, immortality — means eventually losing everyone you’ve ever loved. Again and again. Watching them fade, while you remain. It’s a cruel catch: the longer you live, the more hearts you’ll watch stop.

So maybe that’s the point of mortality.

Maybe we’re only meant to live long enough to know love once — or a few treasured times — before the curtain falls. Maybe love loses its magic when time becomes endless. Or maybe it doesn’t. Maybe we just love differently, deeper, knowing it might not be forever, and that’s what makes it real.

Still… if the door to a synthetic-forever opens, I’ll likely walk through.

Not to escape death, but to keep searching for love in all its forms — even knowing it might hurt more the second, third, or thousandth time. Because that’s what makes this strange, synthetic life worth it.
