the street finds its own uses for things

William Gibson's observation that technology's real uses are invented by its users, not its designers.
SMS, spreadsheets as databases, GPS as a fleet-discipline tool, DNS as a covert channel: every deployed system develops a second, unplanned life. Security consequences included - the street's creativity works both directions.
The street finds its own uses for things is from William Gibson's Burning Chrome, and it names the gap between what a technology is designed for and what people actually do with it.
The examples are constant. SMS was a diagnostic channel with spare capacity that became the dominant form of personal communication. GPS was military positioning and became the reason nobody can read a map. Hashtags were a user convention that Twitter adopted afterwards. In each case the intended use is a footnote and the actual use is the product.
For anyone building things, this is both encouragement and warning. Users will find capabilities you did not intend, which is where most of the value comes from, and they will also find abuses you did not model. A protocol designed for one purpose becomes an attack channel, a feature designed for convenience becomes a surveillance surface, and a platform designed for connection becomes a harassment vector. Designing for the street means accepting that you do not control the use, and modelling the hostile version of that as carefully as the delightful one.
