Here’s the pitch: a motivated group of talented Rust OS developers could build a Linux-compatible kernel, from scratch, very quickly, with no need to engage in LKML politics. You would be astonished by how quickly you can make meaningful gains in this kind of environment; I think if the amount of effort being put into Rust-for-Linux were applied to a new Linux-compatible OS we could have something production ready for some use-cases within a few years.
