The 70's, The 80's, The 90's, The (?)
Will we call it "The 10's?" The first decade of the 21st century, that is. It somehow doesn't sound right. Also, when we get to the 30's, how do you think we'll refer to the 20's? After all, the 1920's are already a decade that many can commonly refer to, and simply saying the 20's will imply 1920's rather than 2020's to most people. I don't think the Y2K problem was nearly as potentially serious as the confusion the decade naming situation will cause. I don't know why I'm thinking of this. Pretty useless, but hopefully something humorous will come of the solution.
