Speaking of technological advancements. This picture might just blow your mind. For the launch of the (at the time, state of the art) CD-ROM in 1994, Bill Gates staged a photo of himself next to these piles of paper.
The disc in his hand was able to hold all of the information that the papers contained, in a much easier to transport circle. Of course, now, the CD-ROM feels laughingly old-school. Things move quickly in the world of technology.
