From my readings on the development of robotics and artificial intelligence, we will be able to create "conscious", "self-aware" android-like robots within the next 50 years which would be indistinguishable from human beings in appearance.

So, in order to compete from an evolutionary standpoint, humanity would be then forced to use robotics within themselves to become smarter, stronger and faster.

My guess is that rather than replacing our bones with metal bars, this will take the form of self-replicating nano-bots which could be injected (like stem cells) and make us literally "superhuman" compared to our current state.

We would become hybrids while maintaining our biological humanity. We would be able to communicate through telepathy, go for weeks without food, have total recall of any subject and even breathe under water. The lines between human and android would blur, all in the name of competing.
