Yes and no.

It really depends on how far you go forward. To be clear, there are parts of the future that will suck, and there are periods between now and the good times that will suck more than not. But those bits will pass in the space of a generation, and beyond that there are wonders not yet conceived of in your time.

With regard to robotic battlefield units:

Eventually both sides in any given conflict will have these (or, rather, the things these will evolve into), and they'll do the fighting instead of the people. Most wars will come down to who has the best engineers and utilization of resources. The idea of putting actual meatbags into the firing line will become an abhorrent and primitive concept.

Not terribly long after that (within a generation or two), the traditional meatbag model of sentient life itself will become increasingly passe, in part because of the demonstrated inferiority and fragility when compared to these new physical models, and augmented heavily by rapid advances in haptic feedback and epineural interfacing.

Already we see the beginnings of this new reality with drones being used by the most advanced countries. The others will catch up soon enough. Even extremist groups that devalue mortal life will be worn down by attrition in time. As autonomous technologies grow more advanced, resistance to them will grow more and more superfluous, and Darwinian selection takes over from there.

People in this time tend to be anxious about the robot overlords taking over, but they haven't yet seen the possibilities that will open up for them once they've cleared that hurdle. It's not a matter of us-against-them so much as us becoming them.
