Maybe. I'm not sure if the original author's intent was to say how risc-v could be better or to say it is bad and people should use other (proprietary) ISAs instead.
I am sorry if my point was not clear enough. I don’t advise anybody to stay away from it. In many ways it is good enough.
I just think that if you were designing something from scratch, you could actually learn from past lessons, rather than publishing a document saying you learned, and then demonstrating conclusively that you didn’t.
Before this, the author has never recommended others stay away from RISC-V, just stated their own distaste for it and a personal preference to use any other ISA if given a choice.
