I really love the structure Angular brought to our front-end softwares. At some point, we may include React to optimize the rendering of our realtime dashboard.
If you are smart enough you can make every code fit your need and reach the code quality you need.
JS weakly typed ? Seriously learn on how to adapt your coding style. I've built more than 20 API/Apps and Node is the best thing I ever had to build networked apps.
I have a J2EE/Spring, Python and RoR background, NodeJS/NPM took the best of every stuff created before.
In my case, I need to be fast and JS + NodeJS + his awesome community permits me to build stable, innovative solutions and high performance networked app in a very short amount of time.
We are in a world of inter-connected apps. NodeJS is for that.
Adapt yourself.
I need hacker modules to accomplish and solves problems of my current worlds, hacker offers me that.

By the way, one more time, thanks Xavier Niel, he's the only one in France who invests so much money on things like this and taking so many initiatives to make things change.
He gave us the cheapest contract for mobile phone in the world, he offered us the 42 school (free school for computer sciences with an innovative learning method), he offers us the most efficient dedicated servers for a decent price (http://www.online.net/fr/serveur-dedie/comparatif-serveur-de...), and so much more.
