This song is talks about how everything has changed since the 20th century. People used to have to work for things they wanted, where as nowadays we are just given the stuff we want without working for it. The cars we drive now have automated systems, instead of cranking up the windows. We used to use cassettes to record music, now we have CD-roms and/or technological devices such as iPods and MP3 players. Nothing is the same as how it used to be. This is what she is getting at through out the whole song. Pretty soon we will be having robots do everything for us, it's the honest-to-God truth.
