My take on this:

The drawing appears to provide a tongue-in-cheek analysis of the modern world, where physical books are merely obstacles rather than sources of information. Those in the maze are not reading the books, they are simply lost amongst them. No one cares for books anymore; traditional research requires physical effort in sourcing, locating and absorbing the material. The fish signify evolution. They are able to escape the outdated confines of formative education and said books by rising above them. They are swimming through the borderless span of the Internet, where one can venture anywhere without the effort of traversing a literary landscape. They rose above the maze itself and are unconfined and, due to their inherent success, they outnumber those individuals still feeling their way blindly through the maze.
