Resort to name-calling if you really must. None of that will change reality.
Rust is not stable, as you yourself have readily admitted. What I've unfortunately had to be pointing out for such a long time now is absolutely correct.
We've been told that we can expect Rust 1.0 by the end of the year. As each month passes, it becomes less and less likely that we will actually see this. We are still seeing significant change, even as recently as the past month.
I think Rust could potentially be very useful. But that requires stability, and that in turn is something that appears more and more elusive each day.
It's easy to say that Swift isn't a competitor to Rust, but the reality is that it is. And unlike Rust, it will very, very likely be usable for serious apps within a few months. It will see the adoption that Rust could have had, had it been usable, further reducing Rust's future changes.
