70% of engineering organizations have now achieved widespread adoption of AI developer tools.
Yet only 31% can actually prove productivity gains with data—and 81% have already given AI agents write access to their code repositories.
FusionAuth teamed up with LeadDev to survey 591 engineering leaders and developers for **The AI Impact Report 2026**. The takeaway: AI adoption has left the experimental phase behind, but it has completely outrun measurement, governance, and workforce planning.
Key findings from the 2026 benchmark:
- The Security Gap: Agents are committing code and calling production APIs at machine speed. Yet 24% of teams simply hand agents human credentials, and 32% have no agent access policy in place at all.
- The Measurement Gap: 62% of teams face tool cost challenges, while 58% say token tracking is completely ineffective at measuring real engineering output.
- The Skills Gap: Architectural thinking is up, but 42% say engineers are losing their ability to debug without AI assistance.
- The Roles Gap: 62% of engineering leaders expect to hire fewer junior developers, creating an apprenticeship crisis for the next generation of engineers.
As Dan Moore, Senior Director of CIAM Strategy & Identity Standards at FusionAuth, puts it in the report:
"AI has moved from assisting developers to acting for them: writing to repositories, reviewing code, calling production APIs. What it exposes is an old problem: most stacks were already over-permissioned, and AI now runs that access at machine speed... AI is probabilistic by design; the identity that decides what it can reach has to be deterministic. AI can assist. Identity decides."
Before your next budget or hiring review asks you to defend your AI spend, see where the industry truly stands.
