I find some of your comments very aggressive. Yet you are lecturing people about being condescending. I honestly much prefer pcwalton's tone which I find much less condescending, interestingly.
Pointing at code can be indeed useful, but it looks to me like you are comparing apple to oranges: Rust is not at 1.0 yet, so comparing code that isn't yet production-ready with Go or whatever technology that is already mature is not all that useful.
Saying that, in it's current state, Rust is not a good choice for production code is acceptable and fairly obvious. Extrapolating to the point of saying that it is doomed seems like quite an exaggeration to me, and not respectful of the work people are putting into this project.
