x86 only missed the mobile market because of multiple bad business decisions, otherwise ARM (and RISC architectures overall) would have been relegated to more decades as backwater architectures.
There is nothing inevitable about anything as Apple controls its own silicon very tightly, Microsoft hasn't even really transitioned away from x86, and Android probably isn't very keen to transition away from ARM.
Now, embedded markets are different but they've always been different and the number of embedded programmers is dwarfed by non embedded programmers and regular users will for a long time never install an app on RISC-V.
It's an interesting journey, let's see where it takes us in 20 years.
This is mostly because their approach to SIMD is so different, but also because I can't test it at all. Are there any RISC-V "machines"? that one can use to do something useful or fun with that someone here could recommend?
I guess it would be fun seeing all my SIMD-fiable use-cases become orders of magnitude faster on RISC-V, too, but I sadly never hear anything about machines that use RISC-V.

To me it sounds like they're creating RISC-VI before RISC-V even winning the market.

I am cautiously optimistic about the future of RISC-V. It is likely to start biting at the heals of ARM in another 5 years or so, and having no licensing fees makes it very attractive in that sense. Qualcomm and Apple will be very interesting in avoiding as many ARM licensing fees as possible even if initially in embedded systems. But it also allows for a lot of hardware to be locked down just like ARM and so it might not be so great for the end users. Time will tell.
All I know is that I look for the seeing Apple Silicon 2 launching in 2036 using this stuff. ;)

Yet there are still a lot of great projects around, that may end up in China grey market chip fabs at some point.

ARM64/AArch64 is about constrained consistency, but most RISCV standards groups still fail to recognize their ISA version fragmentation was a serious mistake. So no, it won't exist outside niche use-cases until the kids stop arguing over what RISCV even means in a general end-user context (example: BOOM flags.) =3
