I've had this in my career also, I've had a solution that was deemed too risky to release by management but would have prevented an outage, but when an outage actually happened that was the first thing they wanted to try and it worked gloriously. I'm thinking that if it was released prior to the incident it would have not have had the same impact on my career.
Regardless of the minimal time with LLMs, I think he hit major points on importance of clarity of abstractions, unreliability, shipping more features and working harder than even and losing touch with the underlying implementation.
