> This is also why I question niche programming languages like Rust when they claim to be suited to systems programming or even kernel development. That’s simply not true when they only run on a small handful of operating systems and CPU architectures.
My understanding is that Rust runs on ~90 platforms. https://forge.rust-lang.org/platform-support.html How many platforms would you like to see it support before you'd say it supports more than a small handful?
(I agree that portability is important)
