Almost all of those points are true of any mainstream architecture (x86, ARM aren't going anywhere, your skills are valuable today, you don't have to throw away any code anytime soon, Rust works today on both) and the others ("chip of choice for AI", "defacto standard", "simplicity means less bugs") are either entirely arguable or outright naivety, they don't say anything unique. The ISA being experimented with and extensions being made is certainly an undeniable plus, though. People on this website just hype it to outrageous levels because the ISA is all 95% of them interact with at any level, and sometimes not even then, so all other factors/considerations are completely ignored in favor of just believing it's really The Best (and I say that as someone who owns real RISC-V hardware and am writing my own emulator, and want it to succeed.) But you don't have to just make stuff up to sell it. You can just say "It's a pretty good ISA, it's freely available/modifiable, and there's a ton of good tooling already available for it". That's a pretty good sell on its own, to be perfectly honest.
