I still don't understand. Your own "evidence" is completely anecdotal.

I and others (including the author of this post) have seen engineers who don't understand what the different components of the "agent system" (as TFA calls it) are, or what they are responsible for. So it's not "projecting their own learning", this actually does happen. Is it so hard for you to believe engineers, especially junior engineers, have a bit of a mess in their heads about how some things work, and need explanation?

If our anecdotal experiences are silly, then so is yours.
