La Vanguardia interview: Cecilio Angulo Highlights the Key Role of Critical Thinking in AI Use

Cecilio Angulo, Scientific Coordinator of the UPC–Siemens Energy ENIA Chair in Artificial Intelligence and Sustainability, was interviewed on January 29, 2026, by La Vanguardia for the feature “Beyond ChatGPT: the AI skills you need to be the most productive and valuable for companies.”

In his interview, Angulo emphasizes that artificial intelligence works on probabilities, not certainties, and warns about the risk of mistaking plausible answers for absolute truths. For this reason, he stresses the importance of critical thinking and human oversight in professional AI use.

According to Angulo, the real differentiating value does not lie solely in the answers AI provides, but in the ability to ask the right questions, evaluate results critically, and understand the limitations of AI systems.

"AI can greatly speed up work, but final responsibility remains human," he says — a key message for professionals and organizations navigating an increasingly digital world.
