David Gross, awarded the Nobel Prize in Physics in 2004 for the discovery of asymptotic freedom, fears for the future of our society. The physicist maintains that the combination of geopolitical tensions and uncontrolled technological development creates an environment of extreme fragility for civilization. The researcher presents this statement as a calculation of probabilities based on the fragility of global institutions, without a specific date. That is, technological advances can threaten humanity if diplomacy and ethical control do not advance at the same pace as innovation. Gross moved his method of quantitative analysis from theoretical physics to the study of the great challenges of humanity. "The chances of you living 50 years [more] are very small," he explained in an interview with 'Live Science'. The physicist estimates that the annual probability of suffering a nuclear conflict on a global scale is currently around 2%, which reduces the estimated life expectancy of civilization to just 35 years if current trends are not reversed. The end of strategic disarmament treaties and the presence of nine nuclear powers have dramatically raised the danger compared to the Cold War era, he argued. One of the aspects that most worries Gross is the growing military automation and the possible delegation of defensive systems to artificial intelligence. Faced with the need to make strategic decisions in a short time, senior managers could choose to entrust operational control to automated agents. "If you play with AI, you know that sometimes it blows your mind," the Nobel Prize winner warned about the unreliability that this technology offers. Delegating global security to technologies that are susceptible to failure represents, therefore, an intolerable risk that adds to the climate crisis and the lack of international cooperation. Although his calculations are negative, Gross insisted that his words translate into an urgent call for prevention and dialogue before technology escapes human control.
