Rust is already at a good level when you are writing low level OS infrastructure code and CLI utilities.

For GUI software or GPGPU development, it still needs to mature a bit more.

Yes, though I think patterns are starting to emerge that will start taking hold. For example: https://raphlinus.github.io/personal/2018/05/08/ecs-ui.html

I mostly think this is a gap in common libraries at the moment and decent coding practices. We’ll see what happens with all of that.

Personally I’m more focused on web-backends, micro-services, and DNS, so GUIs don’t generally present problems for me.

Thanks for the link, it is quite interesting read.

I’m gonna have to disagree with you there: once you turn off std, you’re off the map. Building a syscall handler for example, or implementing VM or even a simple bootloader is non-trivial and has taken me like 10x the time it would in C. If we want rust for device drivers, we need a more sane method of implementing std below userspace. The fact is that C is dead simple and currently contorts more easily. The cognitive load is two orders of magnitude less. Until Rust is this easy, we will use C at work.

Given that I loved doing systems programming in Turbo Pascal, Oberon, avoid to use C as much as possible, focus on Java, C# and C++, I do love a bit of straitjacket in name of security.

I do agree though that it might need still some ergonomic improvements to earn the hearts of other developers that don't share this opinion.
