Samsung Built The Future Too Early

In 2013, Samsung built a phone that tracked your eyes. The front camera watched where you were looking and paused your video the moment you glanced away. It kept the display on as long as it detected your gaze. It scrolled your emails based on the tilt of your head. Every reviewer called it gimmicky. Most owners never used it. But here is the part nobody talks about: almost every single feature they mocked became standard technology within a decade. Attention-aware displays. Gesture control. Dual cameras. Contactless interaction. All of it is normal now. So the question worth asking in 2026 is this: was the Galaxy S4 a gimmick-filled disappointment, or was it simply ten years ahead of everyone who laughed at it?
