Wow, really that is nice! What is your interest in RISC-V? Just general technology interest or do you dabble with things like micro controllers?
I mean my personal prediction has been that RISC-V will dominate in specialized systems not in general purpose desktop PC. As I wrote in my co-processor story, I think ARM is going to replace x86 on the desktop and in the cloud.
However I think we are increasingly going to see graphics cards, coprocessors, AI accelerators and that sort of thing running RISC-V.
I also think low cost hobbyst oriented PCs running Linux will start arriving. You got the HiFive Unmatched at CrowdSupply which you can already buy for $679.
But as you point out, China is a dark horse in this race. Their possible interest in RISC-V could push the platform forward a lot faster than we anticipate, even for general purpose computing.
I am not holding my breath though. My hope is more in with getting a rich selection of RISC-V alternatives which can replace AVR chips and ARM chips in the embedded space.
I quite liked AVR, but 8-bit registers is kind of limiting when programming in assembly. Although there is a certain charm in dealing with these limitations.
I would love to see something like this based on RISC-V in a DIP packakge (Dual in line): https://en.wikipedia.org/wiki/ATtiny_microcontroller_comparison_chart
