If you are really concerned with this why are you posting on a forum literally owned by a SV Billionaire?
Buts let's pretend you are rational. How does a master in chemistry grant you knowledge of mechanical, structural, and fluid engineering. If you say they're both Math/STEM fields, then why aren't chemistry professors, and comsologist certified electricians? It's related by the same logic.
Only if you fall prey to logical fallacies. Noting that not all engineers are motivated to be maximally honest doesn't require that you completely mistrust literally everyone. False dilemma.

What is it, exactly, that you think I'm concerned about? And how concerned do you think I am?
I can't help you with your chemistry/STEM straw man.
How is this a strawman? Because it is literally the crux of your argument that a masters of chemistry is an expert on structural engineering and fluid dynamics?
Even if those engineers clearly have a financial incentive to make biased claims?
