Generative artificial intelligenceGenerative artificial intelligence (AI) refers to models that autonomously create novel text, code, images, or other content from patterns learned during training. This chapter explores how such systems can simultaneously strengthen and weaken professional self‑efficacyself‑efficacy. Where AI delivers rapid feedbackfeedback and new cognitive scaffoldingcognitive scaffolding, it deepens mastery experiences and accelerates skill acquisitionskill acquisition.

Drawing on BanduraBandura’s four sources of self‑efficacy, historical comparisonshistorical comparisons to earlier technological shiftstechnological shifts, and contemporary organisational case studies, the chapter argues that confidenceconfidence is preserved when AI augmentation is paired with transparent workflows and deliberate up‑skilling.
