The technological landscape is evolving at an unprecedented pace, fueled by the convergence of artificial intelligence (AI), the Internet of Things (IoT), and the demand for on-device intelligence and privacy preservation. Among the most promising innovations in this space are three cutting-edge trends: Artificial Intelligence of Things (AIoT), Federated Learning, and TinyML. These concepts are not merely academic—they are rapidly redefining how data is processed, shared, and acted upon in real time, across devices ranging from industrial machines to personal wearables. As digital systems grow increasingly distributed and intelligent, these emerging trends are enabling new efficiencies, breakthroughs in automation, and significant advancements in ethical data use and energy-efficient computing.
