I’ve developed a habit of listening to videos during my bike ride home after work. This week, I came across a video by XPIN about RISC-V. The video presents a viewpoint: RISC-V, as an instruction set architecture, suffers from severe fragmentation in its chip products, which poses significant challenges to the development of its application ecosystem. Therefore, it’s argued that fragmentation must be addressed through unified standards to achieve rapid development. This perspective reminded me of my years of experience using Linux, Android, and the R language, leading me to believe that the video’s argument might not be entirely accurate.
