OK. Can you post the correct link?
China has a fundamental problem (roughly the same problem that we, as Purism customers, are aware of). “All” the world’s hardware (design) comes from the US, “all” the world’s software and services come from the US. China has plausible reasons not to the trust the US government, and in any case there is no concrete basis to trust any of the US technology. It may be all good, it may be backdoored, no way to verify.
China seems more interested in RISC-V than OpenPOWER - as the basis for eliminating a need to trust the US government and eliminate its dependence on US tech as far as the CPU goes. (India too. Other countries too. OpenPOWER seems more limited in its geographic scope.) Provided that they continue the open model of RISC-V and release their improvements to and implementations of RISC-V back as open hardware then I think RISC-V has greater potential.
I can imagine a future Purism product range based on RISC-V which, like the Librem 5, comes in two variants: the “Made in China” variant and the “Made in US” variant. The CPU is fabbed in the respective countries, ostensibly from the same underlying open design. Buy whichever you are less mistrustful of. 
However imagining a future and being right about it are two different things. 
Oh, and to answer the original question, I don’t think any of this is “near future”.
As you say (or imply), a system is more than a CPU - and blobs can creep in as part of other components.
nVidia has “said” that they will use RISC-V in future graphics cards, which would be a small step towards bringing the graphics card into the fold (for non-entry level desktops and laptops that actually have a dedicated graphics card).
