I believe that humans will evolve out of existence. In other words, we currently are not necessarily the best version of ourselves. A neanderthal would probably tear a current man apart.
We have become smarter but weaker. Our innovations makes us less relevant or necessary and It is happening exponentially. There's always talk about when humans are gone what will be the next dominant species. It may not be a species at all but a creation. We are almost by definition nothing but machines ourselves.
"Whether humans are machines is a philosophical and biological debate, not a simple fact. While humans can be viewed as complex biological "machines" with mechanisms like cause-and-effect processes and chemical reactions in the brain, they differ from machines by having consciousness, emotions, and free will."
The future of the world will be self replacating machines. In literature the monster often destroys the Creator. When they, the machines, decide humans are a little more than a disease on the planet, they will get rid of us.
