Are Wikipedia, Twitter, Facebook, LinkedIn or GMail systems of global importance? If they are not, I'm really curious what is your definition of global importance. Their core functionality has been developed in languages such as Java, Scala, PHP and JavaScript. And when looking at the lowest level, everything runs on OSes written in C (Linux, Solaris), webservers written in C or Java (!), and databases / datawarehouses written in C and Java (!), so even your argument that C++ is being used for all the low-level critical stuff is strongly exaggerated.
Sure, as I said, C++ has some place, but nowhere near being the one and only language to implement such stuff, including database engines, webservers and operating systems.
