Yeah, that situation was a, "We've been perfectly fine managing bigger projects with Excel and emails for years."
But that's an extreme case for example. Much of the time it's in a gray area.
Is this guy refusing to use JS because it's a buggy language or because it threatens his 7 years of PHP experience? Is React Native really that bad or does it just threaten this guy's native iOS experience? Is it some expert instinct to put semicolons on JS code or just FUD?
The true experts usually develop a kind of instinct for danger, so you probably want to trust them when it's FUD.
It goes a lot deeper than just seeing this person have X years of experience. You have to filter them for quality years of experience.
Is it a bad sign that this guy is willing to take a 30% pay cut from his qualifications? After all, the best people want to be challenged. Maybe he wants less workload so he can focus on a side project. Or it could just be that he has no intent of actually improving, just wanting a good enough job to pay the bills.
