Overview
This essay from zhichai.net uses a playful bilingual pun—replacing the word "jiang" (疆， territory) in Du Fu's Tang Dynasty poem *Qian Chu Sai VI* with the name of drone maker DJI (大疆)—as a lens for examining the ethics of drone warfare.
The original poem, in the post's rendering:
> 挽弓當挽強，用箭當用長。射人先射馬，擒賊先擒王。殺人亦有限，列國有大疆。苟能制侵陵，豈在多殺傷。
(Draw the strongest bow, use the longest arrow. Shoot the horse before the rider; capture the king before the bandits. Killing has its limits; each state has its territory/DJI. If invasion can be stopped, why kill so many?)
Key points
- From bows to flight controllers: Du Fu's principle of maximizing weapon effectiveness parallels DJI's technical evolution (e.g., the Matrice 350 RTK's 9.2 kg max takeoff weight and 55-minute endurance). Modern "strength" lies less in physical power than in algorithmic resilience—sensor fusion and visual positioning that keep drones flying under GPS jamming.
- "Shoot the horse, capture the king" as precision strike: The author links these lines to modern decapitation tactics—Azerbaijani TB-2 drones destroying tanks in the 2020 Nagorno-Karabakh war, and a UN panel report on a modified DJI drone in Libya attempting to track a commander's satellite phone signal. Cheap commercial drones have "democratized" these capabilities.
- "All states have DJI" as technology diffusion: Citing Conflict Armament Research figures quoted in the post (74% consumer market share; up to 89% of drones in conflict zones), the essay argues ubiquitous drones create a new deterrent logic of "mutually assured transparency," while ending any single actor's technological monopoly—drones become battlefield infrastructure, like electricity.
- The humanitarian illusion: ICRC's concern that precision lowers the political cost of war; UN-cited data from Yemen suggesting lower direct civilian casualties from drone strikes (~12% vs ~32% for conventional airstrikes) but roughly five times wider psychological trauma. The post introduces the concept of "algorithmic exemption"—accountability becomes untraceable as autonomy increases.
- Fragile safeguards: DJI's geofencing reportedly gets cracked in conflict zones within ~72 hours; the Return-to-Home feature has been exploited to hijack drones; "drone contamination" (crashed drones, leaking lithium batteries) emerges as a new environmental hazard.
- AI on the horizon: Open-source projects deploying YOLOv8 object detection on DJI onboard computers point toward fully autonomous targeting; the post cites a UNIDIR simulation with a 17% misjudgment rate for AI drones in urban environments vs 3% for human operators, and DARPA experiments where AI-controlled aircraft entered unpredictable spirals.
Conclusion
The essay closes by returning to Du Fu: technology cannot substitute for human restraint. The rhetorical force of "why kill so many?" is a warning, not a boast—when technology makes killing easy, preserving the principle of "limits" is the real question, one that rests with operators, policymakers, and citizens rather than in the machines themselves.
