that's just not how it works at all though is it. Good luck writing the kernel, firmware etc in a completely memory-safe way. And even if that was accomplished, memory safety isn't the only class of vulnerabilities, it's just the most common.

If they kept a stable version with no updates or new features *ever*, only security patches, for decades, then maybe that could be possible, yeah. But Apple users aren't exactly the kind of people who would enjoy such stability and security anyways, it comes with the compromise of novelty. Stability and security aren't very fashionable either.

edit: Obviously a "memory-safe way" means no `unsafe` blocks in Rust, too.

edit#2: This is all assuming we don't get true AGI. I hope my assumption is right
