Nothing else, I think what the're more concerned with is how open an architecture is.
I think with RISC-V if you wanted to design your own chips and stuff you can just do it, whereas ARM doesn't let you do that.
I'm not about to build my own chips so it doesn't matter all that much to me but I understand where the person is coming from. They'd rather write assembly for the more open architecture.
Exactly what I am doing: I have even a small interpreter to run RISC-V machine code, to a certain extend ofc, on x86_64, and I could just do that on arm64 too: since The 'R' is RISC-V, means "Reduced", such implementation is more than reasonable, even for one average dev.
