> In automotive safety critical systems ISO 26262 is a legally well established, necessary (but not necessarily sufficient) prerequisite for that. That is true, but an ISO 26262 qualified toolchain is neither sufficient nor required to achieve certification. It certainly helps when the auditor looks at your project, but you can also opt for other measures. So you could build ISO 26262 certified software in rust even before the Ferrocene qualification, and you still can build it using stock rustc, but it's more work. Few people will do that and rather opt for a qualified toolchain. > What I meant here is that I'm not sure if what exists today (including Ferrocene's certified toolchain) is enough to make Rust happen in safety critical automotive applications. It's one of the foundational pieces, but others are qualified libraries and the entire ecosystem. So the adoption will by necessity still take time. We do have a few exciting things in the pipeline there, but that's news for another day (it's christmas soon, not all presents at once)
