"we should use X, it's obviously the best"
"but nobody here knows how to use X except you"

At which point the terminally engineer-brained will short circuit and throw a tantrum, because they are used to information just flowing from one data structure to another with the right tweaking, but human brains and education don't work that way.

This is an excellent idea, I am going to discuss that with the family. My dad gets phished constantly, he's pretty savvy but he also has early dementia, so between that and AI, it's going to get harder in the future.

Part of it is also "engineer brain", where you see problems in terms of a rigid system of rules and forget that most problems in real life outside of engineering depend on rules and systems but also human beings. Unlike a structural member in a bridge or a piece of code, human beings are weird, proud, scared, emotional and smart enough to get out of following rules when they don't want to.
