Can confirm the author (not me) has been doing web and system development, including React dev, for over a decade. His complaints are borne of his own frustrations.

A decade of work experience doesn’t necessarily give them insightful insights. Especially if they don’t even know the core point of the topic at hand.

Hackernews became reddit. Sad days.

You’re trying to reduce someone’s 10 years of experience just because they have different opinion than you.

They can have whatever opinion they want, but if they fail to grasp the basics of the topic, then that opinion should remain theirs alone.

While I agree in principle that 10 years of experience can also mean '10 years of being a substandard developer in every way', what basics do you feel are missing here?
