Well JS is forced upon us on the browser and not everyone is tremendously happy about it. It has improved, but still. Plenty of folks out there will seek other languages, we will never all fully agree on what's good on the backend.
BTW - are we positive JS will have a monopoly on browsers 5-10 years from now? (I'm talking about WebAssembly). Cos if the monopoly is gone JS will die a violent death I think.
