Basin of Attraction
The gravitational well of increasing returns holding a paradigm in place—accumulated advantages creating switching costs so high that marginal improvements from challengers cannot escape the basin, requiring categorical disruption.
In dynamical systems theory, a basin of attraction is the region of state space from which all trajectories converge toward a particular stable equilibrium. Arthur applied this concept to technology markets: the basin is the accumulated network effects, installed base, institutional investments, and psychological commitments that hold the dominant paradigm in place. A marginally better product cannot escape the basin—the switching costs exceed the marginal advantage. The challenger must offer categorical superiority overwhelming the entire accumulated weight of the incumbent's increasing returns. When such advantage arrives, the transition is not gradual but a phase transition—the basin itself reorganizing around the new attractor.

The old software development paradigm's basin was deep. Technical lock-in: decades of investment in languages, frameworks, development methodologies, deployment pipelines created an interconnected ecosystem where changing any component required adjusting everything depending on it. Institutional lock-in: organizations structured into specialist teams reflecting high translation costs between domains. Educational lock-in: universities built curricula
