Estévez's lecture “Lessons from the Arts” was organized by IESE and Essentiabcn and held on Tuesday, 23 September 2014, at the Schools of the Sagrada Família designed by Gaudí. During the lecture, Estévez spoke on topics such as Gaudí's faith in his mission, the hope he placed in architecture and his love of work. A group of world leaders from UNICEF attended the lecture.

Estévez also participated in the Gaudí 1st World Congress, which was held in Barcelona from Monday to Friday, 6-10 October 2014, where he presented the paper “An Evolution in Gaudí's Legacy Towards Biodigital Organicism”.

The paper was presented as a publication during the congress and at the proceedings and describes Gaudí as a precursor of the current field of parametric architecture and as the inventor of the first computers applied to architecture. According to Estévez, the exquisite organic continuity of Gaudí's works is increasingly echoed in works in the field of digital organicism, which now consolidated as the first cutting-edge movement of the 21st century and is evolving towards biodigital organicism.

The Gaudí 1st World Congress offered the scientific community a new perspective on Gaudí by presenting unpublished studies, documents and works by Gaudí with the focus on the church at Colonia Güell. Known as Gaudí’s Crypt, the church was the architect's laboratory and the starting point of his new forms and revolutionary working method. The congress also aimed to present the image of an all-round Gaudí and his values and solutions, as well as practical 21st-century applications of his ideas in fields such as architecture, engineering, design, business, creativity, tourism and audiovisual communication.
