Developer Productivity Research

Google internal study (2024) — Reported developers using AI completed tasks 20-30% faster. But noted quality concerns with AI-generated code in code review.
Stack Overflow Developer Survey 2024 — 76% of developers using or planning to use AI coding tools. Trust in accuracy was mixed, with only 43% trusting AI output “a great deal” or “to a moderate extent.”
