Earth in the time of Jordan Keerigan-Smith is set slightly into the future but it has not changed significantly.
By Emily's time alien technologies are starting to be more common, and by Jason's time things have changed quite a bit. probably not as much as they realistically would in that amount of time, though.
when I began writing this story I was very concerned about realism. by 2014 I reached the point of being very unconcerned about realism. thus, my representation of future earth written after this time will probably tend to diverge more from what one might expect given current trends.
