AI coding tools show modest productivity gains of 20-30% in controlled studies, but real-world impact remains limited. While 84% of developers use AI tools, trust has declined from 70% to 60% since 2023. The main frustration is AI generating "almost correct" code that requires debugging. AI excels at greenfield projects and boilerplate code but struggles with complex legacy systems. Despite individual speed improvements, organizations see no measurable gains at the company level due to bottlenecks in code review, testing, and deployment processes.

<p>the trust decline is the key stat here. going from 70% to 60% trust is significant. developers use the tools but are becoming more skeptical of the output quality</p>
<p>i think the root cause is that ai tools dont have good structural context about the codebase theyre working with. they pattern match on surface level stuff and generate plausible but wrong code. thats part of what caliber (<a href="http://github.com/rely-ai-org/caliber" target="_blank" rel="noopener nofollow">github.com/rely-ai-org/caliber</a>) tries to address. better context = better trust = actual productivity gains</p>
