In 1989, Universal Pictures released the movie Back to the Future Part II. It starred Michael J Fox and Christopher Lloyd and was the second movie of what is one of the greatest trilogies ever made. Part of that movie takes place in the year 2015. In that universe by 2015 there were flying cars, hover boards, and self lacing shoes. Holographic movies were a huge fad and newspapers printed events moments after they happened.
Of course 2015 didn’t turn out that way, though Nike has a self lacing shoe. Cars still need roads, sorry Doc Brown, and, despite some valiant attempts, boards need wheels or waves to move.
