He stood in front of a room full of experts and told them something they were certain was impossible. The idea sounded absurd. To build a machine so precise it could carve patterns smaller than the wavelength of light itself. When Hiroo Kinoshita first proposed using extreme ultraviolet light for chipmaking in the early 1980s, the reaction was immediate. They laughed, they mocked him, they said this was fantasy. The laws of physics, they insisted, would not allow it.

And yet, the idea did not disappear.

Years later, others would take up the same “impossible” vision. Engineers building on foundations laid by pioneers such as Kinoshita, pushed forward despite decades of skepticism. Each step revealed new barriers. Mirrors had to be polished to near perfection, light had to be controlled in ways never before achieved, and entire supply chains had to be invented from nothing. It was one breakthrough after another, each as unlikely as the last.

Still, they persisted.

Today, nearly every advanced computer chip on Earth depends on ASML’s extreme ultraviolet (EUV) lithography machines, the practical outgrowth of that once-ridiculed idea. What began as a theoretical impossibility now powers modern life—from smartphones and smartwatches to laptops and consoles; from the computers steering our cars to the 5G and Wi‑Fi that link us; from the data centers running our apps to the artificial intelligence behind our searches and recommendations—all built on a process many believed could never exist.

To the yogis, what appears impossible to the ordinary mind is often only a reflection of its current limits. The reasonable mind adapts to the world as it is. But progress belongs to those who question whether it must remain that way, and to those, like Kinoshita and the engineers who followed him, who keep pushing until the world adapts in turn.

What was once impossible becomes inevitable, only after someone refuses to let it remain so.
