I can promise you it doesn’t make a shred of difference to the victim if they get their brains blown out of their ears by a sniper a mile away, burned alive by white phosphorus, ripped to pieces by high explosives, crushed under a tank, frozen solid by nerve gas or melted by neutron radiation. It was routine what 80 years ago to gas civilians. The only reason it wasn’t employed on the battlefield was that it was as likely to kill your troops as the enemies. Violating that ban is inevitable - as soon as one country adopts a ‘more discriminating’ method of killing and gains an edge, the rest will follow suit. They’ll sell it saying a drone would never accidentally kill a non combatant. The naivety of suggesting the technology can’t be developed with the pace of change we’re witnessing is astounding. They certainly can make a micro railgun, probably already have secretly. And I doubt a micro drone needs much more current than a pacemaker provides, especially with an energy efficient SoC at the latest fab.
