When it comes to the future, there's really only one authority on what it'll be like. That, of course, is the Back To The Future trilogy. They went everywhere in those films, including the 80s, the 50s, and, um, the wild west. They also provided a glimpse into the future, taking us all the way into 2015 in Back To The Future Part II.
So if 2015 was their future, and we've already passed 2015, that logically means that the future is already here. Surprisingly, the makeup artists who "aged" Michael J Fox for the 2015 scenes did an incredible job. In this photo, the BttF Michael J Fox is on the left, and the actual Michael J Fox in our 2015 is on the right. They're pretty much the same!
