We're mostly just bitter from years of being beaten with it. I can't actually face using node.js as an example. It is physically painful compared to other options that I have dealt with (flask, asp.net). Also for me, I've been burned before. Do you remember when everyone jumped on the PHP bandwagon? That. Again. Look where we are now.

On the web, and now suddenly on the desktop, velocity is not what we need. We need quality and consolidation. Down the line can you see any ES6 based API lasting as long as win32? Hell no. Why would I want to risk building a major capital product on such guarantees?
