Episode notes
Broader 2025 Survey Scope
- Stack Overflow received just over 49,000 developer responses across 166 countries for the 2025 survey.
- The survey expanded AI questions, adding agent-specific usage and workflow items.
Shrinking Pipeline Of Junior Developers
- Stack Overflow sees a long-term decline in 18–24 year old respondents dating back to 2022.
- Erin correlates this with broader labor trends showing fewer entry-level hires and tougher placement for new graduates.
Developer Satisfaction Is Recovering
- Developer happiness rose from ~20% to ~25% reporting they are happy at work year-over-year.
- Erin views the change as meaningful and tied to reduced churn and normalization after 2024 turbulence.
