In the ensuing years, the LHC indeed triggered a revolution in particle physics, but not of the kind I was expecting. (Image: CERN)Gian Giudice is Head of CERN’s Theoretical Physics department. At the time I joined CERN as a fellow in 1993, particle physics had just gone through a heroic period. In the ensuing years, the LHC indeed triggered a revolution in particle physics, but not of the kind I was expecting. AI is already revolutionising all aspects of experimental data analysis but it could also transform how theoretical physics operates.
