I've seen average users do this sort of thing, or assume a computer comes preinstalled with anything you could ever possibly want, but it's just head-shaking

to see 20-something engineers not know what should be a basic concept.
It's not just IT. Even outside the field, I've worked in places where black employees were suspected of stealing or misusing stuff that had little intrinsic value or made no sense to even swipe in the first place.
In any given field, certs are only useful if there is some sort of tangible benefit associated with them. The moment they're watered down or marketed to the lowest common denominator, they lose both prestige and credibility. With IT as jeetified as it is now, I wouldn't trust any of them who claim to have certifications.
