The Future

Do you think:

Rust will be the new C?

Clojure will be the new Java?

Go will be the new C++?

Perl6 will be the best thing about Perl?

Ruby and FIOC continue their legacy for a few more decades?

Haskell will use superior_snake_case instead?

ARM will overtake x86?

C doesn't die because its just at right sweet spot in the abstraction/performance spectrum.
A language that has more abstraction(lets call it "Blub") makes programming easier but imposes a  performance penalty(e.g. overhead/GC) and its abstractions forbid lower-level optimization.
A language that has less abstraction(lets call it "Abacus") requires too much manual labor and its performance advantage is matched by inline assembler of C.
