Ask HN: Will the C programming language really die?

There is too much talking about Rust programming language and it's great that research on this topic is vibrant.

My question.

Will the C programming language really die? Meaning, stop being used as a System programming Language or in the Embedded Systems field.

It is still worth to invest some time digging these topics with the C programming language?

Newbie here, don't be rude.
