Sorry, Atlas, you have to take a number to pick on me. Your number is 92. I am now serving number 4, but perhaps this will keep your mind occupied while you wait:
What do you suppose your teacher meant by that strange aphorism?
1. That any person who would ask a question, was by dint therof, stupid? And the corollary; that any person who suppressed a question, was therefore smart?
2. That all people are stupid?
3. That the particular respondent, e.g. me, was stupid?
..1.. is contrary to my experience.
..2.. may be true some of the time, but not all of the time.
..3.. see 2
To me, the aphorism suggests that the teacher used it as a way to keep the class quiet and shut down their creative development so they would listen complacently to yet more pseudobabble.
Which I find disappointing, coming from someone whose job is nominally to reduce ignorance.
;--- back on point,
The Original Post, as posed, suggests that the protagonist engineer speaks first, asking a question, perhaps to no one, more likely to someone farther up the chain of command.
If you ask questions aloud of yourself, you may become a subject of discussion. If you answer yourself, maybe you will merely be perceived as the weird engineer who thinks out loud.
If you ask the posted question of a peer, the response will probably be an answer, or a shrug.
If you ask the posted question of a person of superior rank, you have to understand that that person is probably not equipped to answer a technical question, is not willing to go out on a limb over a style question, is likely to interpret any open ended question as a polite way of leading up to a suggestion, and may have been specifically trained to deflect any question with a mirror response to gain time to think of an answer and consider its political consequences.
I.e., if you ask a question of anyone but a peer, and don't have a putative answer of your own ready, you will be perceived as ... well, being strange, or not being the sharpest knife in the drawer. Since engineers are paid to be sharp, it could even be a career decision.
That's why I think the lawyers' aphorism is appropriate for engineers, too; certainly in the stated scenario.
