I don't think this was super important given the core goals of the project. I agree that effortless tagged unions are a very valuable feature in a language, but it's also one that is paradigm shifting and requires a different set of goals.
Without naming names, there is a language out there with some overlap with Zig's domain that does have really good tagged unions. But that project has a different set of goal than Zig's and that's okay. They're both good projects.
An alternative: `zellij` is better is better. With `tmux` I never get the sense that I have "mastered" it. I simply don't know all the controls - I only have a few of my most commonly used ones. Stepping into `zellij`, I feel like I've mastered it within a few hours of using it.
How does copyleft license work in this case? Aren't they legally required to open-source their sources and publish it publicly or can they hide that behind a request system?
Partly because it's an ecosystem that I'd like to see grow. More people using it means that the other Rust-based projects I use will be better too.
Partly because it is the "carbon fiber" of programming languages. Just its use is something you can use to market to other engineers.
Partly because it's very ergonomic and I enjoy working with it. I'd much rather dive into esoteric Rust code than esoteric C code.
Partly because code written in of Rust will have less errors than code written inside of C. It isn't just memory safety - it's all of the type theory/best practices we figured out in the last 50 years.
I understand why it was written in C. It's an easier language to work with and they probably needed something out quickly. But coding in Rust is a sign (not proof, but a sign) that a program is of quality make.
And the largest benefit of modern technology comes from the fact that so much of it is "free" (ad-supported). Without ads, there would simply be no effect at all.
If this is true, then there's a chance that there's no secret sauce to GPT4 that [Google doesn't already know about](https://arxiv.org/abs/2006.16668).
I think that whole thing was a bit overblown. RHEL is free for individuals. When I need the stability of a server OS, I'd rather just use the real thing.
