These works drew comparison to Jules Verne. Unlike Verne, he proposed inventions integrated into everyday life, not creations of mad scientists, and he imagined the social developments that arose from them, often with accuracy: social advancement of women, mass tourism, pollution, etc. His La Guerre au vingtième siècle describes modern warfare, with robotic missiles and poison gas. His Téléphonoscope was a flat screen television display that delivered the latest news 24-hours a day, the latest plays, courses, and teleconferences.
