It's important to note that the available libraries for each language varies a lot, and the best performing ones are proprietary for the most part. Fortran, for example, has a set of proprietary libraries that many employers buy that have been continually optimized for nearly 50 years. Both C and Python can readily bind to Fortran libraries, but for other languages like R, Matlab, Mathematica, etc. this is a major disadvantage.
