I agree with pretty much everything you said - and thanks for sharing your perspective. Node.js is still very young and the enterprise ecosystem has a long way

I agree with pretty much everything you said - and thanks for sharing your perspective. Node.js is still very young and the enterprise ecosystem has a long way to go, but it's getting there (e.g. IBM's acquisition of StrongLoop, the EnterpriseJS initiative - https://enterprisejs.io https://enterprisejs.io) I've done a bit of work with Erlang, which is all about the 9s (though it doesn't have the enterprise ecosystem on par with Java or .NET around it) but for a lot of software, Erlang is an overkill, as would be formal verification for example. A lot of software is just fine being built with Node or other young tech trading stability for productivity and time-to-market.
