If you already have the hardware, I wouldn't switch just because of the license myself. ARM is still ahead in perf/watt and the environmental impact for the existing box is already spent.
I am glad to see the ball moving forward for Risc-V, I do hope they avoid some of the vendor locked extensions that many ARM based SBCs seem to face. Feels like anything other than RPi so far has been an exercise in relative frustration. I have my SiFive 2 that I haven't played with yet... with the work I saw a few weeks ago with Haiku might be fun to play around with.

- sylware 3y agoThe license and the "modern" ISA is so much important, I am ready to pay the price there (non performant critical anyway, should be fine and increase risc-v momentum).
- brucehoult 3y ago> ARM is still ahead in perf/watt Citation needed. The Cortex M23 and M33 seem to have made a good step forward in efficiency compared to RISC-V, but those are microcontrollers. I haven't seen any indication of the Cortex A53/A55 being more efficient than the U74, or the A72 being more efficient than the C910. In fact the reverse. Maybe the A510 / A515 / A520 is better, but you can't buy an SBC with those. > the environmental impact for the existing box is already spent. That is certainly true.
- sylware 3y agoHow much "environmental impact" are you ready to pay to get digital freedom from a toxic IP (non royalty free) like ARM (same for x86)?
