>Some of these novel side-channel attacks actually even apply in completely unrelated architectures such as ARM [1] or RISC-V [2]. Possible? Yes. But far less likely. Complexity carries over and breeds bugs. RISC-V is an order of magnitude simpler than ARM64, which in turn is an order of magnitude simpler than x86. And it is so w/o disadvantage[0], positioning itself as the better ISA. 0. https://news.ycombinator.com/item?id=38272318 https://news.ycombinator.com/item?id=38272318
