The Root Cause of Never Learning
May 26
In this episode of Root Cause we sit down with Adrian Hornsby — former AWS Principal Engineer, founder of Resilium Labs, and author of Why We Still Suck at Resilience — to get to the root cause of what's quietly breaking inside engineering organizations as AI absorbs more of the thinking. We dig into the gap between how we imagine our systems work and how they actually work, why that gap is where all the real learning lives, and what happens to a team when the thinking itself gets delegated to something that sounds confident but doesn't know which walls are load-bearing.
