A faculty member who left consulting to teach at Dartmouth described how the arrival of ChatGPT in late 2022 upended early experiments in curriculum design. The instructor developed a course on AI and consultative decision-making and reports that generative AI has introduced unpredictable disruptions requiring iterative pedagogical change. The account stresses that disruption often begins in unexpected academic places and that course designers must iteratively adapt assignments, assessment and academic integrity policies. Departments should consider rapid faculty development and cross-unit coordination to manage AI’s classroom effects.
