I caught a different meaning from this entire sentence. I think the author was alluding to the fact that even if you replace a technology with something "better", at the end it doesn't matter, because Most People will keep using Twitter, Most People will keep using QWERTY layout, count all of your acquaintances, I doubt any of them speak Esperanto.

Well at least the idea comes through, but I don't think it makes sense to argue whether Lua is actually better than JavaScript or not.
