   Yup. I've ported my employer's product to, um, quite a lot of 32- and   
   64-bit architectures over the past thirty years. It runs on servers,   
   desktops and high-end mobile devices Five years ago, I was looking   
   forward to doing a RISC-V port to Linux and/or Android before I retired.   
      
   Then SiFive made job cuts and abandoned development of high-end   
   general-purpose cores in October 2023. Since then, there doesn't seem to   
   have been much in the way of performance advances in the RISC-V space.   
   Ahead Computing was set up to offer that, but have gone rather quiet.   
   MIPS switched to RISC-V, but have been acquired since then.   
      
   I'm starting to become suspicious that the claims that it's hard to make   
   very fast RISC-V cores are accurate.
