Well known people in the industry such as Dave Jaggar, Jim B. Keller and Dave Ditzel give RISC-V the thumbs up.
The more I write about RISC-V the more realize how controversial RISC-V is in many circles. It is not uncommon to see claims that RISC-V is a bad design by RISC zealots trapped in the 1980s. The question is: How much stock should you actually put in random people on the internet making such claims?
Ideally, you should judge a design on its merits, but if that is not good enough for you, then perhaps you can respect the opinions of well-respected microprocessor designers. Here are a few of them making remarks on RISC-V.
