If this can get the non-C programmers to learn and understand the usefulness of a simple, minimal and direct language ("modern" languages are just too bloated), it is well worth it.
I have said it before and say it again; C will allow you to program everything from itty-bitty MCUs to honking server machines. It is also the de-facto universal "glue" language and its real-world benefits far outweigh any perceived difficulties.
Bottomline - Every programmer should know C whether you use/like it or not.
