It's not _just_ a self-fulfilling prophecy - there are other factors at play here beyond simply "X is good enough". But sure, the more that dominant languages try to pick up good features from other, better languages, the more they will tend to maintain their dominance. This is the way nearly all successful systems behave, incidentally. Please note that it's going to be tough sledding trying to convince JS users not to try to improve their language so that some other clearly superior language can come along and take its market/mindshare.
And, well, yes, I realize we're talking about a future maybe-feature. That said, I assume you're granting my counter-point about how, no matter how you slice it, this is still ultimately "just a babel plugin"?

My point is that there's no "clearly superior language" compare to JS. Some people want a ML flavor, some people want a C# flavor, some people want a Lisp flavor. I wish people would just use those language and improve the interops instead of putting everything into JS.
