Before Infinity Stones and even a hint of Thanos, Marvel opened with an unironic MySpace reference, point-and-shoot cameras rather than a cellphone, and pictures, not selfies. The godfather of the Marvel Cinematic Universe debuted more than a decade ago, and its age is showing like a dad at a middle school dance. But Stark predicted a lot of the significant modern comforts we enjoy today -- except for one, but more on that in a moment. Below are some of the major technological advancements the movie had before the rest of the world. 

Tony Stark, the billionaire playboy philanthropist, is at the cutting edge of technology for his time and uses a video calling service to get in touch with Obadiah Stane about the sale he just pulled off. This was two years before Apple announced FaceTime in June of 2010, a service that would herald in widely available video calling. To make matters worse, Stark doesn't use an iPhone or an Android to make these calls. He uses an LG VX9400, which is a flip phone.
