Evetually it will, around about the point that either (a) speed becomes the norm in high-level languages or (b) we're forced to concede that the two are allies: Higher-level languages are implemented using lower-level languages, and the main thing you do with lower-level languages is implement higher-level languages. (For the latter option, especially if you use the word language somewhat loosely - e.g., a TCP stack isn't a programming language, but TCP is a somewhat higher-level abstraction, and it's best implemented using lower-level languages.)
