Rust is not vaporware under any reasonable definition of that word; there is plenty of Rust there to run. It is not stable yet, to be sure; but there are plenty of people happily using it, some even in production.
The person you replied to did not say that Rust is vaporware.
At worst, it says that Rust's toehold is tenuous enough that even vaporware could replace it. I don't agree with that, but I can understand the sentiment. Think "knocked back with a feather".
