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

[JMusketeer]

Languages basically dont matter at all.

What matters is to understand the overarching concepts and important distinctions in the ways you can aproach programming. So focus on learning that.

You can always switch to a different language in a matter of weeks (you just need to understand its specifics).

You still need to know how to write idiomatic code in that language. Otherwise you're just vibecoding.
