This is the nature of tech now (perhaps the whole time due to being a relatively "new" field). Most people don't have the slightest clue what they're doing beyond their ability to parrot buzzwords.

Mean? Sure. Reality? You betcha. It's incredibly rare these days to encounter truly competent professionals. Most are just hoping the guy below them doesn't know enough to spot their shortfalls and speak up.

This aligns shockingly well with Uncle Bob's rough stat: “The number of programmers doubles every five years or so. This means that half the programmers in the world have less than five years of experience.”
