"Information" is one of those words (in English and other romance languages) that are blessed/cursed with a deliciously filigreed constellation of meanings. It's not that it's lacking a definition, but rather that there exist any number of definitions, each context-dependent, that are largely mutually exclusive. Information theoreticians will, from a technical perspective, think of Shannon's work — whilst mortal humans will recall aphorisms such as "information is power," and ponder on the relationship between information and wisdom.
Irrespective of this, there's broad consensus across a variety of au courant academic and applied fields of research that "information" is an increasingly fundamental concept of study. This is surely no news to fields whose very nomenclature encapsulates the term (viz., "information theory," "bioinformatics," etc.) — but is also equally true for fields as diverse as computer science, systems theory, synthetic biology, and linguistics.
