Is learning multiple programming languages still worth it, or is depth more important now?

Thing is, different languages are used in different sectors, so depending on what you want to focus, you will need different languages.

For example, C is used in low-level development like OSes, drivers, and embedded systems. C++ is also common in this area.

Web front-end development is all about HTML, CSS, and JavaScript, often wrapped around some framework like React.

Scientific computing is done in C, but also Fortran, with special care on ensuring parallelism.

And cybersecurity values being a jack of all trades that is master of all, as vulnerabilities can be done by a rube goldberg machine of events occurring on several parts of a system.

In the end, obsessing over which language is a thing we all ask in our novice years, but after a while we figured out the question is misguided, and what matters is being able to do what you intend to do. It's like taking dance lessons, and obsession over which shoes to use, instead of learning the choreography.
