IMHO, the author is completely wrong and the sentence "C is the desert island language" is closer to reality (see http://www-cs-students.stanford.edu/~blynn/c/intro.html). The fact that such a poor language remains the single sane choice to build the kernel of Linux is a proof of the lack of languages. C++ was already a mess in 98. Python started as simple but has added more and more complex syntaxes. Java is in the hands of Satan, Ada is too verbose, nobody takes the effort to learn it, Haskell and SCALA are niche languages not so easy to learn...
IMHO, there is a need for a polyvalent language that would enable development of Linux kernel (low level and performance), that would be easy to learn and that would enable quick development (dynamic typing, syntactic sugar, ...).
