AI Failures Are Human, Not Technical: An Eight-Point Fix
This article argues that most AI project failures are not due to technology but to human and organizational issues. It outlines eight common problems: unclear user intent, mismatched tool selection (agent overuse), unmet user expectations, lack of oversight, insufficient context, imprecise language, missing evaluations, and undefined outcomes. Citing studies and incidents like the Replit database deletion, the author emphasizes the need for better human decisions in AI adoption. The piece provides an actionable checklist for each issue, focusing on intent-based design, appropriate tool usage, setting expectations, implementing least-privilege access, providing rich context, using structured prompts (CARE), establishing evaluation sets, and defining measurable outcomes.
- A 2025 MIT study found roughly 95% of generative AI pilots deliver no measurable impact.
- Gartner predicts over 40% of agentic AI projects will be canceled by end of 2027.
- Gartner estimates only about 130 of thousands of vendors claiming agentic capability are genuine.
