My read of it was “the C-suite hates when the engineers actually know how shit works, and the leadership must kowtow to the people doing the actual work.” YMMV or the commentor may have meant something completely different.

Not my style, but recasting a seriously impressive piece of engineering as a manga character… <chef’s kiss!>

For anyone unfamiliar with, or unphased by steam locomotives, may I suggest Animagraffs’ walkthrough of the Union Pacific Big Boy? https://youtu.be/Hszu80NJ438 And while I’m at it, all of his “How [thing] Works” videos are absolutely stellar.
