What is the future for human?
This is a very wide open question. It could be two directions. One direction is that human would just disappear like the dinosaur.  One direction is that human would become a species like a god. For the first direction, it may be caused by many situations. e.g. Nuclear war from WW3, extreme climate change. For the other direction, reproduced energy is ready, all cancers can be cured, everything can be done with robot with AI, human life is unlimited.
