Mystérieux message SF venu de 2100

Create a 15-second photorealistic cinematic sci-fi mystery short film. A young man in his late 20s is alone in a modern apartment in Dubai at night. His smartphone suddenly receives a mysterious video message labeled "MESSAGE FROM 2100." He opens it and sees an older version of himself, around 70 years old, sitting in a futuristic room. The older man looks terrified and urgently says: "Whatever you do... don't go outside tomorrow." The video suddenly glitches and cuts to black. The next morning, the young man cautiously walks toward his apartment window and looks outside. Reveal a breathtaking futuristic Dubai in the year 2100: enormous advanced skyscrapers, futuristic transportation, flying vehicles, glowing architecture and a transformed Burj Khalifa. But the entire city is completely empty. No people. No cars. No activity. The man slowly looks up toward the sky. The clouds suddenly separate, revealing an enormous mysterious unidentified object hovering above the futuristic city, so massive that it dominates the entire skyline. End on a dramatic wide shot of the tiny man standing beneath the gigantic object.
