In this workshop we investigate “alternative futures” of programming with generative-AI tools. The workshop aims to establish a strand of HCI research on the future of AI-supported programming that goes beyond the current focus on usability and performance of GenAI-assisted programming tools, to instead explore radical re-conceptualizations of co-coding and co-creation with AI. The workshop is open to researchers and practitioners engaged in critically exploring novel ways of coding and interacting with AI-based programming tools. We encourage speculative design inquiries exploring prototypes, and provocations that facilitate engagement with a wider spectrum of human skills, experiences and ways of knowing when programming with AI. The workshop welcomes contributions that i) present examples of novel interaction, empirical studies or prototypes of AI-based programming, ii) re-conceptualize how programming with AI-based tools may be conducted and designed for, iii) reflect on values and ethical challenges of AI-based programming.
