"Those who play with the devil's toys will be brought by degrees to wield his sword"
About this Quote
The subtext is a critique of the modern habit of calling consequences “unintended” when they were structurally predictable. A toy becomes a weapon when institutions discover what it can do at scale: surveillance justified as convenience, optimization sliding into exploitation, engineering brilliance conscripted by militaries, advertisers, or authoritarian states. Fuller’s diction makes that conscription feel almost physical: the toy graduates into the sword, and the player becomes the wielder.
Context matters: Fuller wrote and spoke in an era when invention was inseparable from total war, nuclear escalation, and the emerging systems-thinking view of Earth as an interconnected design problem. As an inventor, he’s not moralizing from the sidelines; he’s indicting his own tribe. The line is a compact ethic for innovators: don’t confuse the sandbox with innocence, because the sandbox is where you learn the grip.
