I&#x27;m not an employee of any of those companies (though the one I DO work for is moving to Elixir and Node away from Ruby) so I don&#x27;t feel I should comment on that.<p>However they all are very active in the conference circuit (and on their engineering blogs) talking about their <i>current</i> work in Node.<p>Its not unfair to ask but not everyone can give you the kind of information you seek.
