Let’s examine why your comment was interpreted as a troll statement.

Message you responded to was asking if the captions actually matched what was said by this individual. The second bit notes the individual is known to be “full of it” which generally means “speaking nonsense, lying, or exaggerating”.

Last I heard, musk has regularly exaggerated in his statements. And I believe has been known to lie on occasion.

So, you have an honest question asking to find the source of the clip and your immediate response is, where is your proof he doesn’t know more than anyone else on the planet when it comes to manufacturing.

Either you woefully misinterpreted the comment or you didn’t read it at all or the simplest answer, you’re a troll.
