useless

This term conveys a sense of total failure in utility or efficacy. It is often used to describe objects that are broken or obsolete, but it carries a stronger emotional weight when applied to people, where it suggests a feeling of inadequacy or helplessness in a specific crisis. In a pragmatic sense, it describes actions that are futile, meaning that no matter the effort exerted, the outcome will remain unchanged. This distinguishes it from words like inefficient, which implies a waste of resources rather than a complete lack of result.
