It’s safe to say that World War II would cause a lot of problems, not the least of which is the interruption of Elon Musk’s plans for Mars. In an interview with GQ Magazine, Musk expressed his belief that another World War is definitely a real possibility, and that it would be “far worse” than any war the world has ever seen. He also predicted that the world may see a global anti-technology movement in the future, and that both of these things could seriously hinder the progression of science and technology, including his own plans to explore Mars.
