Is this the history of science fiction?

Artist Ward Shelley has created a fascinating (and also, perhaps, a little ludicrous) infographic (seen above) that displays the history of science fiction. Shelley portrays SF as something of a many-tentacled blob, which is probably both accurate and appropriate. He starts off with fear and wonder (presumably the basis for science fiction in the human psyche) and then goes on from the Enlightenment, and the Gothic novel to pulp fiction and modern movies.

Apparently Shelly created this map as a submission to the Places & Spaces: Mapping Science Exhibit for 2011, which has the theme "Science Maps as Visual Interfaces to Digital Libraries". This map is amazingly detailed, and you could spend hours and hours wandering through its many back streets and alleys (and if all the names and terms on the map were actually somehow linked to some sort of digital library, or even wikipedia, this could become a never-ending journey). Should you want to investigate this future, there’s a rather enormous image of the map here.
