006 The Eras of Science Fiction

If you’ll indulge me, I’m going to borrow the idea of eras from science. These eras are independent of genre as genres are closely tied to the human condition at the time rather than the technology to produce story. I expect that the eras will continue to change faster as we speed toward the Singularity.  I offer free a poster of how the seminal work of a new scifi-genre  maps into an era.
