We need vision to seize the opportunities of the digital transformation, and the inventiveness of filmmakers is a shining example of this. From "Star Trek" to "Back to the Future," many of the major sci-fi flicks have dared to take a visionary look into the future. Some of the technology that filmmakers dreamed up back then has long since become reality. Our image gallery shows which visions led to actual inventions, and which ideas are still just dreams for the future.
