I miss some options...as in

• Nuclear holocaust: that looked like something very likely to happen when I was a child... planing how to build my own bunker was one of my favorite pastimes then!
• The christian apocalypse or well, any other future where paranormal things become normal like the earth being invaded by demons, ghosts, vampires, etc.
• The human race transmutes into something different, like all our consciences being transferred to a computer. Or amebas (has anybody read Seedling Stars?).
• Idiocracy.
• We get to a point where machines do everything for us (work, art, etc.).
• Our creator reveals to us and removes all the suffering from the world. Everybody is happy ever after.
• Genetic engineering becomes a commodity. Everybody can become whatever he wants.
• Immortality too.
