Gentle reminder that all programming languages have their uses; they are just tools, and you need a big toolbox to be able to solve a wide range of problems.
Anyone who insists that a specific technology is the One True Way to succeed as a software developer is the proverbial guy with a hammer who thinks every problem is a nail.
Corollary: any developer worth their salt should be able to learn a new stack relatively quickly. It takes far longer to master a large codebase than a new language.
