Jevons Paradox
As technological progress increases the efficiency with which a resource is used, the rate of consumption of that resource tends to rise rather than fall.
Jevons first described this effect while studying Britain’s coal consumption: more efficient steam engines led to more coal being burned, not less, because the cheaper engines made coal-powered industry economical in far more places. The paradox has become extremely popular in software circles lately, as the falling cost of writing software is making applications economical that would previously have been dismissed as not worth building. As AI-assisted development and other tools continue to reduce the cost of software production, demand for software seems likely to expand correspondingly. Software that was once too expensive to build becomes worth building, so cheaper software is unlikely to mean less software.
