Well, that sure is an arrogant way to present stereotypes as fact. At first, I read this as satire.

You can follow the history of web development and see exactly why the current stack is as it is. It's people building solutions to problems.

For example, nobody thought "I should create a front-end build process to impress my peers!". What happened instead is that repetitive tasks were programmed out of existence.

The web industry is young, you can trace every single steps of it without much research. To claim something as ridiculous as "responded by making the simple things they do monstrously complicated to try to prove something to the C++ guys" is silly at best.

Sure, this may be accurate for some of the junior devs. you worked with in your career. However, this is not representative of the industry as a whole.
