Matthew arrived early at the Sentinel Systems R&D facility, the underground tech lab buzzing with the faint hum of cooling fans, quantum servers, and ultra-high-speed processors running the earliest simulations for Sentinel OS. Today was the first official development day, and everyone on the team knew it was going to be a grueling six months.
The challenge wasn't just writing an operating system—it was reinventing how users interacted with technology. Unlike Windows, macOS, or Linux, Sentinel OS wouldn't rely on physical screens, keyboards, or mice. Everything would exist in a fully holographic 3D environment, controlled by gestures, voice, and predictive AI.
