That said, Torvalds continued, “Rust has not really shown itself as the next great big thing. But I think during next year, we’ll actually be starting to integrate drivers and some even major subsystems that are starting to use it actively. So it’s one of those things that is going to take years before it’s a big part of the kernel. But it’s certainly shaping up to be one of those.”
I don’t know about that, languages which are based on standards (c++ , javascript, c) seem to have much better enduring popularity, i don’t want to see rust becoming less and less popular which will lead to less available developers (like what is happening with ruby).
