Are you joking? Are you running large, mission-critical systems in production on Redox already?

I'm sure it will be good enough for that some day, but that day is not now.

Because of GNU/Linux.

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.

Redox is an unproven toy OS compared to some of the more mature and battletested alternatives. And don't think battletested is a metaphore, some of these have been used to operate battlegear.

I feel like you should add a disclosure about being the creator of Redox.
