The 23rd century will mark the second full century of the world being united under a global parliament and a worldwide federal government. It will also celebrate the second full century of Buddhism and atheism becoming the dominant religions of the world. By this time, society will have become completely matriarchal and spacefaring. Christianity, Judaism, and Islam will become defunct religions. The only languages spoken by human beings will be English, Japanese, Esperanto, Cantonese and Catalan.
