Futurist Thomas Frey: A robot does not kill someone out of fear, anger, or desperation. They kill because someone told them to do it. At least that the way it works with our current generation of robots. What comes next may be a different story.
Normally, when we think about war, it has to do with countries using their armies to fight other countries, or in the case of a civil war, countries torn apart by internal rival factions.
But that line of thinking is far too narrow for the conflicts in our future as our choice of weaponry and choice of battlefront continues to expand.
From my perspective, the traditional country vs. country war tends to be far more about political theater, a theater that plays out on the world stage in full view of the public, than the subversive battles being fought over countless levels of minutia in the background.
