I wouldn't dismiss the node.js stack quite so easily. Those "proven" technologies you mention had to go through their own lifecycle of continued improvement.

I remember a time when my colleagues who were steeped in C++ had a good laugh at my expense because I was building server-side web applications with a new framework and a hot, new language. It woefully under-performed similar C++ applications in benchmark tests.

It was 1998, and the language was Java. I could write my applications much faster and in a more maintainable way than they could, but they didn't care. Their technology was proven, and Java was simply a fad.
