On Tuesday, December 2nd, 2025, 600 members of the Tech, Innovation and Digital community gathered at GRIDX in Wickrange for the new edition of the TNT Symposium. Built around the theme “404 – Reality Not Found”, the event invited attendees to reflect on a world where truth fragments, perception glitches, and technology reshapes the very notion of reality.

At a time marked by the rise of deepfakes, AI-generated misinformation and digital distortions, the Symposium explored how leaders can decode a world of shifting signals, anticipate uncertainty and steer transformation with clarity. Throughout the evening, attendees experienced a conference, a networking cocktail, a gala dinner and live performances, culminating in the announcement of three major awards celebrating excellence within Luxembourg’s tech ecosystem.

Conference highlights: Understanding a world where perception falters

The evening opened with an AI-generated introduction video, immediately immersing the audience in the central tension of the edition: how to distinguish reality from fabrication in an increasingly mediated world. After a welcome speech by Kamel Amroune, CEO of The Dots, Giulia Pescatore, Senior Manager – Strategy & Innovation at Deloitte Luxembourg, took on her role as Master of Ceremony and invited the first keynote speaker on stage.

Maurice Schubert, Partner – Advisory & Consulting at Deloitte Luxembourg opened the conference with a sharp reminder of how accessible and disruptive deepfakes have become, describing their misuse as “depressingly easy”. He warned that AI-augmented misinformation has created a true “crisis of knowing”, where seeing and hearing are no longer enough to determine what is real. Moving forward, he argued, organizations must go beyond detection and work collectively to rebuild frameworks of trust and develop the tools required to identify deception at scale.

Dr. Nesryne Mejri, Postdoctoral Researcher at the SnT, continued the discussion by offering a scientific perspective on deepfake detection. She presented her research on modelling the intrinsic characteristics of real human faces to detect deepfakes, including those that do not yet exist. She emphasized that fighting misinformation is a collective responsibility, calling on individuals, regulators and organizations to stay informed, anticipate risks and support research efforts.

Sébastien Bohler, Neuroscientist, editor-in-chief of Cerveau & Psycho, author and speaker, explored why the human brain is so easily misled in a world saturated with information, showing how novelty, emotion and group influence shape our perception of truth. Drawing on neuroscience and philosophy, he explained that “we believe first and understand later”, a cognitive shortcut that makes misinformation particularly persuasive. He concluded by emphasising the need to strengthen critical thinking to counter these natural biases.

Following these three perspectives on truth, perception and digital complexity, attendees gathered for a networking cocktail sponsored by Proximus NXT Luxembourg before moving into the next part of the evening.

Gala dinner, awards and performances: A celebration of leadership and illusion

The gala dinner opened with remarks by Solenne Niedercorn-Desouches, followed by a moment that captured the spirit of the evening. When Kamel Amroune took the stage, his introduction began in his own voice, until he revealed that the opening lines had been generated by an AI. This brief demonstration showed how convincingly technology can imitate us, and how easily perception can shift.

The program continued with an intervention by Laurent Pulinckx, CIO at Creos Luxembourg (THECIO23), who introduced Éric Mansuy, Group Chief Operating Officer a.i at Quintet Private Bank (THECIO25). Éric Mansuy reflected on the selection process and shared the advice he would give his successor: to remain “authentic, engaged and committed throughout the year”.

Throughout the dinner, the atmosphere was energised by three performances by Les French Twins (Tony and Jordan), whose blend of illusion and digital storytelling captivated the room. During their final act, they incorporated the announcement of the CIO of the Year in a sequence that combined illusion and technological artistry.

Several distinctions were revealed during the evening:

    •    THECIO26: Roberto De Gori, CIO of Ampacet Corporation, succeeding Éric Mansuy (THECIO25)

    •    Tech Firm of the Year: Anidris, succeeding NTT DATA, recognized for excellence aligned with the HITS pillars: Human, Inspiration, Technology and Sustainability

    •    TechForLife Prize: Tech Mahindra Foundation, succeeding Dataspace4Health, honored for its contribution to societal and sustainable impact

The dinner concluded with closing words from MC Solenne Niedercorn-Desouches, who congratulated the winners and thanked the attendees before inviting them to continue the celebration at the dessert buffet and the After Party sponsored by Proximus NXT Luxembourg.

The TNT Symposium 2025 explored the blurred line between truth and illusion in an AI-shaped world. The evening’s scientific, strategic and artistic perspectives highlighted a core challenge: navigating uncertainty with clarity. Under “404 – Reality Not Found”, one message prevailed. Leadership today requires both lucidity and imagination.
