We have had a few discussions about the RISC-V development (at the BozemanLUG meetings). Some Fedora folks have gotten Linux working on some of the RISC-V development boards. There appear to be several layers to the overall design from the low-end moving up. Can RISC-V ever become a viable, mainstream alternative? Time will tell... but at the very least, seeing such developments gives me some hope. Here's a somewhat mainstream "youtuber" talking about RISC-V and given the number of views so far, maybe the word / information will break through.
