Stop relying only on technology. Technology can help the

Hear the solemn words of Isaac Yeffet, guardian of security and wisdom: “Stop relying only on technology. Technology can help the qualified, well-trained human being but cannot replace him.” This is no casual observation, but a warning born of experience, a cry against the folly of those who would place their faith wholly in machines while neglecting the strength of human spirit, skill, and judgment. For the inventions of man are powerful, yet they are but tools, and tools are useless without the hand that wields them wisely.

Technology dazzles the eyes with its speed, its precision, its seeming perfection. It promises safety, comfort, and mastery over the world. Yet Yeffet reminds us that even the most wondrous of machines has no soul, no conscience, no instinct born of life itself. A machine cannot discern loyalty from betrayal, courage from cowardice, or truth from deception. Only the well-trained human being—forged in discipline, sharpened by experience—can see beyond what algorithms and sensors reveal. Thus, to rely solely on technology is to build a fortress with no sentry, a sword with no warrior.

History provides a stern lesson. In 1941, the mighty French fortress of the Maginot Line stood as a marvel of technology—walls of concrete, artillery hidden in steel turrets, tunnels and defenses stretching for miles. Yet the German army bypassed it with cunning and speed, rendering it almost useless. France trusted in machines and walls, but neglected the creativity and adaptability of human strategy. It was not the failure of the weapons, but the failure of reliance on them, that led to disaster. So too Yeffet warns us: never forget that technology is only as strong as the wisdom of those who wield it.

Consider also the realm of flight. Airplanes are marvels of engineering, filled with instruments, computers, and automation. Yet time and again, lives have been saved not by the machine, but by the calm presence of a trained pilot. Captain Chesley “Sully” Sullenberger, when his aircraft struck geese and lost power, could not lean solely on instruments or automated systems. With steady hand and judgment, he guided the plane to land safely upon the Hudson River, saving all aboard. Here the truth is plain: technology assisted him, but it was the qualified human being who preserved life.

The origin of Yeffet’s words lies in his service, in a world where safety depends on vigilance. As a master of security, he saw how airports and nations alike trusted too much in machines—scanners, detectors, cameras—forgetting that behind every screen must stand a mind trained to interpret, to question, to act. He speaks with the weight of one who knows that machines cannot think, cannot feel, cannot anticipate the unexpected. The true guardian is the man or woman who has trained themselves in discipline, observation, and courage.

The lesson, then, is clear: do not bow before the idol of technology. Honor it, use it, sharpen it, but never let it become your master. Remember always that the human mind, disciplined and prepared, remains the first and final defense. Machines may extend our reach, but only wisdom guides our hand. To forget this truth is to walk blind, trusting a lamp without oil.

Practical wisdom lies before you: If you wield technology, train yourself to mastery in your field, for the machine amplifies only the skill you already possess. Do not grow lazy, thinking the tool will act for you. Learn, discipline your mind, strengthen your judgment, and then let technology serve you as a faithful ally, not as a master. In every domain—whether security, medicine, teaching, or leadership—remember that it is not the tool but the person who determines the outcome.

So let Yeffet’s words be engraved upon your heart: technology cannot replace the human being. It may aid, but it cannot lead; it may serve, but it cannot rule. Be ever vigilant, be ever trained, be ever prepared. For it is not the machine that guards the world, but the spirit and wisdom of those who hold the power to use it rightly.
