Bandwidth

In its original technical sense, bandwidth referred to the width of a band of electromagnetic frequencies, measured in hertz. The term appeared in engineering literature by the 1930s and became central to information theory through the work of Claude Shannon at Bell Labs in 1948, whose landmark paper "A Mathematical Theory of Communication" formalized the relationship between bandwidth and the amount of information a channel could transmit. For decades, bandwidth belonged exclusively to engineers, physicists, and the emerging field of computer science.

The metaphorical migration began in the 1990s and accelerated in the 2000s, as internet culture made technical terminology fashionable in everyday speech. "Bandwidth" crossed from server rooms into conference rooms, where knowledge workers began using it to describe their personal capacity for additional projects, meetings, or decisions. The word offered a way to decline requests that sounded more objective and less personal than saying "I'm too busy" or "I don't want to." It reframed human limitation as a technical constraint, something to be optimized rather than respected.

The adoption of bandwidth as a workplace metaphor belongs to a broader pattern in which industrial and technological language colonizes the vocabulary of human experience. Workers become "human resources" or "human capital." Skills become "assets." People are asked to "optimize" and "scale." Each metaphor subtly reinforces the assumption that a person's value lies in their capacity to process and produce, a framing that engineering vocabulary makes feel neutral and inevitable rather than chosen.
