To create is to destroy. This, we have known, and will forever have to think about.
Every innovation will be used to save and destroy. It does not matter how lofty your ideas are, someone will put them to poor use.
Advanced biotechnologies could synthesize plagues, but could cure so many. Nuclear power was used to end thousands, but arguably saving approximately a million from bloody grinding war on both sides. The promise of fusion technology may well save more yet, granting clean power to the world and saving so many more.
To say that a technology capable of granting limitless clean energy can only be used for such a thing, is a pointless endeavour.
Inevitably the demands of war will press it into service...
And inevitably, it will bring life to millions of worlds, with uncountable citizens. No mind of flesh can picture such a thing, and thus it is easy to ignore.
But you would never meet so many in a thousand lifetimes.
Wave Motion Technology is the fire of its time. If used irresponsibly, it becomes devastation. If harnessed, it will bring a new age of prosperity.
In the end, it is not the technology, it is the culture.
