Between Promise and Reality: How AI Researchers Are Rethinking the Future of Health Tech

Important | 2025-11-19

When Dr. Serafeim Moustakidis took the stage at the International Conference on Information and Software Technologies (ICIST), held on October 16–17, 2025, the auditorium at Kaunas University of Technology’s Faculty of Informatics was filled with anticipation.

As the conference’s keynote speaker, he didn’t just discuss algorithms or technical models – he spoke about the fragile balance between ambition and reality in AI-driven healthcare. His insights, drawn from years of experience in EU-funded research projects, offered a rare behind-the-scenes glimpse into what it truly means to innovate responsibly in a field where both human lives and technological limits intertwine.

Data and Consent Challenges

Before any algorithm is trained, researchers face the biggest hurdle: data availability. While setting up a consent process is easy, obtaining participation from enough people to build a robust solution is incredibly difficult, particularly in the case of rare diseases.

S. Moustakidis illustrated this challenge with a cancer detection project, where the emotional state of newly diagnosed patients made it challenging to encourage their participation in providing samples for the trial.

Tiny Devices, Major Challenges

Most modern health devices rely on wearables or smartphones with limited computing power. “We want models that can run on the device itself,” he says. “But mobiles and wearables have restrictions—you can’t fit a huge neural network inside a smartwatch.”

These technical limitations are only part of the challenge. Privacy adds another layer of complexity. “Sometimes you click a consent box without understanding what it means,” he notes. “If we really want trustworthy AI, we have to make sure data stays private and secure.”

“VOCORDER”: Pioneering the Future

Despite the challenges, the VOCORDER project has made remarkable progress, driven by the efforts of an international team of researchers.

The team’s AI model, based on breath analysis, reached over 90% accuracy in early tests. “We were very glad to see that,” he says proudly. Yet he’s quick to caution that technical success is only part of the story. “Research is full of surprises,” he adds. “Everything is unexpected. You set out expecting one thing, and a year later you realize the reality is very different.”

These surprises became all too real when the VOCORDER team faced unexpected data challenges. While they initially aimed to detect multiple diseases, they had to narrow their scope because they were unable to secure enough patient data. For lung cancer, just two patients agreed to participate from a target group of 200, preventing the team from building a workable model.

The Startup Paradox

When asked what advice he would give to startups in the AI space, Dr. Moustakidis doesn’t hesitate: focus on people first. “The most important thing in a startup is the team. Investors don’t fund ideas; they fund people. Find someone you trust – not necessarily a friend – but someone who complements your skills.”

And when it comes to AI itself? “These days, everyone claims to be working with AI,” he laughs. “That’s not a niche anymore. The value is not in the algorithm – it’s in the application. Don’t sell AI. Sell what AI helps you achieve.” The value lies not in the algorithm itself, but in the business case – how the AI helps achieve something specific, providing a tangible, non-conventional value that investors are looking for.

From confusion to understanding

The insights shared by Serafeim Moustakidis at ICIST 2025 served as a powerful reminder to the academic and business communities gathered at KTU: the AI revolution in healthcare is not a smooth, purely technical ascent. It is a journey fraught with human, ethical, and logistical complexities.

His address was not just an update on innovation; it was a clear call to action, urging the conference participants to shift their focus from ‘what AI can do’ to ‘how we can responsibly and successfully deploy it,’ a theme that anchored the subsequent discussions and debates throughout the two-day event.
