Nothing truly comes for free in the world. Everything has a cost, whether it's visible or hidden. Even when something appears to be free, there's often an underlying expense or consequence. In economics, the concept of opportunity cost illustrates that choosing one option means forgoing another. Free goods or services are often subsidised by other means, like advertisements or user data collection. Additionally, societal resources, time, or effort might be expended. Even in nature, there's no true free lunch; every action has reactions and dependencies. Understanding this reality helps us evaluate the true costs and implications of seemingly free offerings.
