Asterinas: OS kernel written in Rust and providing Linux-compatible ABI

Decades ago Linus Torvalds was asked in an interview if he feared Linux to be replaced by something new. His answer was that some day someone young and hungry would come along, but unless they liked writing device drivers Linux would be safe.

This is all paraphrased from my memory, so take it with a grain of salt. I think the gist of it is still valid: Projects like Asterinas are interesting and have a place, but they will not replace Linux as we have it today.

(Asterinas, from what I understood, doesn't claim to replace Linux, but it a common expectation.)

Also this mysterious new Fuchsia OS from Google is also shooting for full Linux compatibility and is about to show up in Android, I think this is a much more realistic path of the next generation of operating systems that have a real chance to replace Linux but who knows what their actual plans are here at the moment but I don’t believe for a moment that that project is dead in any way.
