> an army of formerly PM's, Designers, etc all at once exclaiming "I'm an engineer too!" that should signal that maybe the thing they're doing isn't really engineering Not really disagreeing with your other points but this specific one is an ad hominem. Anyone can engineer, so the only signal to look at is what they are actually doing. It otherwise implies that PMs, designers, etc. can’t be competent engineers, which I do not believe of the competent PMs, designers, etc. I’ve worked with.
