ISA is like a language, we will learn foreign languages, but we will not give up our mother tongue. RISC-V is a great ISA, and it will promote other ISAs to be more open. From ecology, diversity will make Linux more robust. We will continue to improve csky subsystem, and now is only the beginning. Best Regards Guo Ren
