Now that we're living here in 2010, I like to walk around saying things like: "Well, back in the twentieth century, we didn't anticipate the impact of information technology!" Bonus points if I remember to refer to it as the TwenCen or something. Now I just need to find someone who was frozen in ice in the 50s to be my foil.
Also, when I refer to my neighborhood I call it my sector.
I wonder what science fiction will be like in the distant future. I've been looking for Charlemagne-era fantasy novels and haven't found any yet.
