Every 4 years, like the Olympics, all the leading minds (regardless of country or situation) should gather for 1 month and exchange ideas on everything except military technology. They would have to gather online or in different cities; because for security reasons - losing these ppl by having them ALL gathered would set back the world a generation. Agriculture, human sciences, biology, chemistry, earth sciences, language & literature, environment sciences, history, mathematics, psychology, political science, sociology, economics, learning/teaching methods, music theory, art, philosophy, and all branches of engineering are good groups with which to start. Olympics are fun and all but leave little lasting impact on society. . . aside from memories of pretty bodies running around half naked.
