Come on, I really like Rust but these types of comments are why people like Theo de Raadt don't take the evangelists seriously. You can't take a project like OpenBSD that has existed for more than 20 years, is being used right now to power all kinds of applications around the world on all kinds of architectures and say that Redox, an experimental x86-64 OS, is viable competition. What with the seven applications written for it listed on Wikipedia, including "A simple web browser with basic image support" and "A simple editor that is similar to notepad". I don't know what the driver situation is like but I don't expect to see a lot of support for anything beyond the most basic devices.

In general I think the "why don't you rewrite your project in $languageoftheday" remarks should be dismissed and ignored. Theo is entirely right when he says that if people think it's a good idea then they should spend less time bothering the devs about it and more time actually coding it.

You think Curl or Emacs should be written in Rust? Then do it. Don't bother the devs about it. If it's really better then people will make the switch.
