For a long time, people thought babies were just "taking it all in" without much understanding. However, new research shows that even two-month-old infants have hidden intelligence. By using advanced brain scans and AI, scientists discovered that babies' brains are already busy sorting the world into categories, like animals or trees, long before they can talk. This is great news because it helps doctors spot developmental issues much earlier and even helps tech experts build smarter, more human-like AI.
