The opposite of "are current" can be expressed in a number of ways. Words like outdated, old-fashioned, past, ancient, and obsolete all convey a sense of something that is no longer relevant or up-to-date. On the other hand, one might use terms like modern, contemporary, new, fresh, or current to describe something that is up-to-date or currently relevant. Alternately, one might use language that suggests a lack of connection or continuity, such as disconnected, disjointed, or out of sync, to describe something that is not current. Ultimately, the antonym for "are current" depends on the context and the specific meaning being conveyed.
