You said "open source Rust based MK OS..." Does that mean an OS written in Rust? I had not heard of that. As I recall the Rust support for RISC-V is quite limited for now until the LLVM patches go upstream (which will be soon).
I agree with your statement "I have no idea how successful we will be and I frankly do not care." There will be a lot of benefits as a result of this work regardless of the immediate outcome. Keep building the future!
There are a lot of comments here on HN that seem completely uninformed of what's actually happening with RISC-V. They are about to be surprised.
