The Tipping Point (Arthur's Framework)
The irreversible threshold in a positive-feedback system where the balance between competing alternatives snaps—not gradual shift but phase transition, after which the outcome is locked in.
Arthur's tipping point is a precise mathematical phenomenon, not a metaphor. Before the tip, the system can in principle go either way. After it, positive feedbacks favoring the winner have accumulated past any plausible intervention's capacity to reverse the trajectory. The transition is discontinuous—like water crystallizing to ice, the same substance suddenly organized by different rules. December 2025 was the tipping point for AI in software development: the convergence of reasoning capability, context-window size, and conversational coherence crossed the threshold from chatbot to collaborator, releasing pent-up demand that adoption curves measured in recognition speed rather than marketing effectiveness.

The tipping point requires preconditions: pressure building beneath apparent stability, a basin of attraction holding the old paradigm in place, accumulated advantages creating switching costs. Before December 2025, large language models improved incrementally within the chatbot paradigm—question-answering machines, sophisticated search, asymmetric human-directs-machine-executes. Each improvement was noted and absorbed. The paradigm's increasing returns—millions learning to prompt, institutions
