While this is true, sometimes knowing the syntax and basic familiarity with the toolchain can be good enough to start contributing. It's just that help from peers becomes very important - good code reviews, etc and not every organization can facilitate this.

Almost all the languages you'll find on those "requires 10 years of experience on language X" ads are in that "not worth knowing" set.
I prefer Alan Perlis' advice: "A language that doesn't affect the way you think about programming, is not worth knowing."
Edit: I categorize myself as one of the programmers who can learn syntax, but it takes me much longer to understand the language.
