YES. But to qualify, it will if Opal (Ruby -> JS Transpiler) and Truffle are seen for the true and remarkable value that they really are. We are not going to need Crystal (not to say it's irrelevant, compilation is great and has a place, but not to replace Ruby) and such projects and will enjoy a blissful isomorphic platform once folks can really see the value. DHH sadly is too married to other pure JS projects that make him unable to be objective and to lend his allegiance to Opal (he could have been years ago, but it’s political for him now sadly as is evidenced by many various remarks and attitudes), so we have to probably forge this path ourselves so that the “political” figures can finally see the real value. Truffle will be big by itself simply for it’s remarkable speed improvements. OpenSSL is about done and next is Nokogiri a la Sulong, so we’re about to be cooking with gas here. Yet again, going back to Opal, that’s where real magic will happen. For example, a Vue.rb project would be great where we could use Vue with Ruby on Rails and be Ruby completely up and down the stack via a simple Opal wrapper (https://github.com/fazibear/awesome-opal#js-wrappers-bindings https://github.com/fazibear/awesome-opal#js-wrappers-binding...).
