Neat to see the emergence of another major CPU architecture. I guess the main benefit of RISC-V is that any company can make a RISC-V chip if they want. Note that this doesn't mean their chip design is open source or anything; it just means whatever silicon they design implements the RISC-V instruction set.
Seems like Ubuntu is putting resources into it: https://ubuntu.com//blog/canonical-enables-ubuntu-on-starfive-visionfive2-risc-v-board
