What does the future hold for us?

I am thinking now about a future in which the world is not as we know it today. The first thing htat comes to my mind is a world devastated by the nuclear war, that ended with a world dominated by robots that were used as soldiers during the nuclear war to support the radiation of the nuclear bombs. I think this robots were created by the chinese. I imagine little cities built from its ashes, where survivors live, surviviors that lived underground in vaults.
I also imagine animals affected by radiation that suffered changes in their bodies, or new races that lived underground since the humans conquered the whole world and now, that they are gone, they rise up again. The lack of water that killed so many survivors, the diseases that tortured animals and humans until they died or metamorphed to another thing. People running for their lives, from wild people that are looking for being fed from human flesh.
