From Bletchley Park to AI-Driven Healthcare: A Personal Journey Through Innovation
February 11, 2026•9 min read
The intersection of technology and healthcare has always fascinated me. Not just as a professional, but on a deeply personal level.
My Grandad was stationed at Bletchley Park during the Second World War, playing a crucial role in the team that deciphered the Enigma code—a feat that arguably shortened the war and saved countless lives.
His work was a remarkable testament to the power of technology when harnessed for a greater good. Yet, despite the groundbreaking achievements at Bletchley, my family was not immune to the era's harsh realities.
My Grandad’s brother tragically passed away at the tender age of 25 from systemic tuberculosis. A disease that was treatable even then, but only for those who could afford proper medical care.
This stark dichotomy—between technological brilliance on one hand and the inaccessibility of healthcare on the other—has always stayed with me. It has shaped my understanding of how technology can either elevate or exacerbate human suffering, depending on how it is applied.
The merging of technology and healthcare
For many years, technology and healthcare were seen as separate entities, existing in parallel worlds with little overlap. But, from the 1940s through the 1990s, we began to witness the merging of these worlds.
Most of the transformative advancements in healthcare in recent history were made possible through a combination of technology and clinical wisdom. Heart valve replacements, organ transplants, and DNA sequencing are just a few such innovations that have redefined what is possible, offering hope and healing to millions.
As we move further into the 21st century, the pace of technological advancement in healthcare is only accelerating. This rapid change is being led by a diverse group of passionate stakeholders, all working collaboratively to solve the collective challenges faced by modern healthcare systems.
Medicine’s next frontier
Today, with the advent of genomics, precision medicine, and artificial intelligence, we are standing on the precipice of the most rapid evolution of technology the world has ever seen.
AI, in particular, has the potential to revolutionise healthcare in ways that were unimaginable just a few decades ago. It promises to transform not only how we diagnose and treat diseases, but also how we deliver care, by making it more personalised, efficient, and accessible.
We are already beginning to see the real-life effects of this transformation. AI tools are being integrated into healthcare systems around the world, changing the way clinicians work and patients receive care.
Much to my delight (and that of my colleagues and the patients I treat), the AI-based tools gaining traction are those that enhance—rather than replace—the human-to-human work undertaken by clinicians.
My experience has been that AI strips away much of the cumbersome, outdated and time-consuming administrative aspects of practising medicine—giving me more time, space and energy to focus on patient care.
The human cost of administrative burden
For over a decade, I’ve had the privilege of working as a GP.
My passion lies in seeing patients, hearing their stories, and helping them navigate through periods of ill health. For me, there’s something incredibly fulfilling about being able to make a positive impact on someone’s life, especially when they are at their most vulnerable.
However, the reality of modern medical practice is that much of my time is consumed by administrative tasks. For my entire career, I’ve spent hours of every work day (and plenty of nights, days off, and weekends) entering data, writing notes, and managing paperwork.
This administrative burden is a significant contributor to the burnout that is causing many doctors to leave the NHS. It produces what often feels like an impossible struggle to balance one’s passion for patient care with the ever-increasing documentation-related demands of the job.
Living with “the EHR problem”
As technology has evolved, I’ve become more and more excited about the prospect of finding tools that could alleviate some of my administrative burden, allowing me to focus more on what I love—caring for my patients.
But for years, I was a sceptic.
My colleagues and I had seen countless technological innovations that promised to revolutionise healthcare, only to fall short when it came to practical implementation. Many of these tools, while impressive in theory, ended up adding more complexity to my work rather than simplifying it.
In short, the EHR problem describes the fact that as EHRs have become more complex and advanced (all the while promising to save doctors time on administrative tasks), healthcare clinicians have universally ended up spending more time on documentation.
A paradigm-shift with AI
My scepticism about using technology to reduce administrative burden ended when I discovered Heidi.
In my quest for productivity tools, I came across this AI-driven platform designed to support clinicians by automating some of the most time-consuming aspects of our work. Intrigued, I decided to put it to the test one day with my Dad, who has been battling ischemic heart disease, pulmonary fibrosis, and atrial fibrillation for years.
We were sitting in my lounge, with my children intermittently interrupting our conversation to ask for marmite sandwiches or to play FIFA. It was a chaotic environment, not exactly conducive to a clinical setting, and my expectations were understandably low.
But, as my dad recounted his recent medical history, Heidi quietly listened in the background.
To my amazement, within seconds of us finishing, this AI-medical scribe generated a word-perfect clinical note that captured only the salient aspects of the history. It was as if it had filtered out the noise (both literal and figurative), to deliver a precise and accurate summary of my dad’s condition.
I was blown away.
For the first time, I had encountered a piece of technology that actually helped me—rather than adding to my workload.
Improved efficiency without compromising care
Heidi is a prime example of how AI can be applied in a genuinely empathetic way by truly understanding the pain points experienced by time-poor GPs.
It doesn’t just offer a solution: it offers the right solution, tailored to the specific challenges we face every day.
This is what makes AI in healthcare so exciting. It truly is technology that has the potential to improve productivity and quality of life for clinicians—without compromising on patient care.
Instead, my experience has been that Heidi enhances care quality, by allowing clinicians to focus more on the human aspects of medicine, rather than getting bogged down in administrative tasks.
Healthcare, technology, and humanity
Reflecting on this experience, I can’t help but think of my Grandad’s work at Bletchley Park.
While the stakes were different, the underlying principle was the same—using technology to solve complex problems in ways that ultimately benefit humanity.
My Grandad and his colleagues cracked the Enigma code, altering the course of history. Today, AI like Heidi might not be breaking wartime ciphers, but it’s solving a different kind of enigma: the challenge of delivering high-quality healthcare in an increasingly complex and demanding world.
As we continue to advance, sitting at the intersection of technology and healthcare is an exhilarating place to be. The potential for innovation is limitless, and the impact it can have on people’s lives is profound.
My hope is that we can continue to develop technologies that not only push the boundaries of what is possible, but do so in a way that is truly empathetic and human-centred.
After all, that’s what my Grandad’s work was really about—using technology to make the world a better place. Today, we have the tools to do just that. And I, for one, am excited to see where this journey will take us.
