Why AI Coding Tools Pay Off for Senior Engineers (and Quietly Underperform for Everyone Else)

Andrew and Olena review the gains of AI tools in their work at Pieoneers
Adoption of AI coding tools has reached near-universal levels. The Stack Overflow 2025 Developer Survey, released late last year and treated across the industry as the 2026 reference, found that 84 percent of developers are using or plan to use AI tools, with 51 percent of professionals using them daily.
Trust is moving in the opposite direction. The same survey found that developer trust in AI accuracy fell from 40 percent in prior years to 29 percent. Experienced developers were the most skeptical of all, with only 2.6 percent reporting high trust in AI output and 20 percent reporting high distrust.
Both of those statements are true at the same time. The most-used class of developer tools in history is also the least-trusted by the people who use it most. And yet the same period has produced some of the most striking modernization results the industry has ever measured.
