Oh, those hackers are still hacking, on C and C++ and a few other languages.

All of these cloud technologies? All of this high performance storage, networking, virtualization? It's not written in ruby...

I think the difference is that you're on Hacker News, run by a startup accelerator. It's in their interest (albeit unintentionally as far as I can tell) to create a culture/cult around the value of being the founder, not the hacker.
