Explore the groundbreaking research on programmer interactions with AI coding assistants in this 18-minute conference talk from OOPSLA 2023. Delve into the first grounded theory analysis of how developers use GitHub Copilot, based on observations of 20 participants solving diverse programming tasks across four languages. Discover the bimodal nature of interactions: acceleration mode for known tasks and exploration mode for uncertain scenarios. Gain insights into the changing landscape of programming with AI assistants and learn about recommendations for improving future tools. Presented by researchers from the University of California at San Diego, this talk offers valuable perspectives on the evolving relationship between programmers and code-generating models.
