Highlights

Andrew Ambrosino, who leads development of the Codex desktop app at OpenAI, discusses how AI is fundamentally reshaping product development. He argues that the most valuable skill in an AI-first workplace is no longer implementation, but 'taste'—the ability to curate, direct, and make strategic decisions. The conversation explores how this shift is collapsing traditional roles, changing team structures, and creating new challenges for planning and design.
