Why AI will never replace the one thing patients need most: human care.
When most of us hear the words artificial intelligence, we imagine robots replacing people. In healthcare, the reality is far more reassuring. AI is transforming the way doctors diagnose disease, but it isn’t replacing the expertise, empathy or judgement that patients depend on.
For Dr Aobakwe Segwe, radiologist and co-founder of the Centre of Medical Imaging (CMI), the future of medicine isn’t about choosing between technology and people. It’s about using both to deliver better care.
Today, AI can analyse thousands of medical images in seconds, detect subtle abnormalities and assist specialists in identifying patterns that might otherwise take much longer to review. In fields such as cardiac imaging, these intelligent systems are already helping radiologists work more efficiently and accurately.
But there’s an important distinction.
“AI provides an additional layer of clinical support, but the final interpretation and responsibility always lies with a specialist,” says Dr Segwe.
A scan is never just a picture. Every image belongs to a person with a unique medical history, symptoms and life circumstances. While AI may recognise a pattern, it cannot understand the bigger clinical picture, have difficult conversations or help someone navigate the uncertainty that often comes with waiting for a diagnosis.
The moments patients remember
Anyone who has ever waited for the results of an MRI, CT scan or X-ray knows that the hardest part is often the waiting. Behind every scan is someone wondering whether their life is about to change.
Dr Segwe believes those moments remind us why compassion remains one of medicine’s most powerful tools.
“The way someone explains the procedure, answers your questions and recognises your anxiety can stay with you long after the appointment is over,” she says.
As technology takes over repetitive administrative and analytical tasks, it may actually give healthcare professionals something increasingly valuable: more time to connect with patients. Rather than replacing doctors, AI has the potential to free them to focus on the conversations, reassurance and clinical decision-making that machines simply cannot provide.
Closing the healthcare gap
Across Africa, access to specialist healthcare remains one of the biggest challenges. Many communities have limited access to radiologists, creating delays in diagnosis and treatment.
Digital imaging and connected healthcare systems are beginning to change that. Medical images can now be reviewed remotely by specialists in different cities or regions, while AI can help prioritise urgent cases so patients who need immediate attention are identified sooner.
Yet Dr Segwe cautions against believing technology alone will solve the continent’s healthcare challenges.
She believes Africa also needs to invest in research based on its own people, diseases and healthcare realities.
“Research should reflect the people it serves,” she explains. “Developing African evidence allows us to improve diagnosis and treatment based on our own patient populations rather than relying solely on international data.”
That means creating medical knowledge that is relevant to African communities, ensuring better diagnosis and ultimately better patient outcomes.
Smarter, not simply newer
In a world fascinated by the latest innovation, Dr Segwe believes healthcare should ask a different question before investing in expensive technology: Will it genuinely improve patient care?
Sometimes the answer isn’t buying an entirely new machine. Upgrading software or improving existing equipment can often deliver meaningful clinical benefits while making healthcare more accessible and affordable.
For patients, that’s encouraging news. It shifts the focus away from impressive technology and back to what really matters: receiving accurate diagnoses, timely treatment and compassionate care.
A future built on trust
The healthcare of tomorrow will undoubtedly look different. AI, advanced imaging and digital systems will continue to reshape how medicine is practised. But according to Dr Segwe, the heart of healthcare should remain unchanged.
The future isn’t artificial. It’s profoundly human, with technology working quietly in the background while skilled clinicians do what they’ve always done best: care for people with knowledge, empathy and trust.
