I stopped listening to what Canonical says. They often get involved in things and disturb the ecosystem then abandon stuff or dig a "not invented here" hole.
Unity, Bazaar, Mir, Upstart, Snap, etc.
All of them had existing well established projects they attempted to uproot for no purpose other than Canonical wanted more control but they can't actually operate or maintain that control.
While its current performance is not competitive, there are currently interesting options. I got the orange pi riscv version, mainly to test riscv while it's slow compared to other arm socs, it's still better than I expected. There are even risc v TPUs now.
i've been hearing about arm computer for almost twenty years and only just recently general-purpose decently-priced arm laptops have been released (qualcomm laptops, the macbook neo).
and arm desktop are still not a thing, in practice.
I think the Surface Laptops (2018?) count, and arguably the previous models (2012+) sorta-kinda count (tablet + keyboard).
Side note: It's kinda funny to me that "the keyboard is detachable, the screen is glass and you can touch/write on it" makes it "lesser" than a laptop rather than being an upgrade.
But yeah, definitely happy to see more in this space. Now we just need e-Paper laptops to take off as well :)
This is true, but only for the bigger players. The nature of hardware still fundamentally favors scale and centralization. Every hyper-scalar eventually gets to a size that developing in-house CPU talent is just straight up better (Qcom and Ventana + Nuvia, Meta and Rivos, Google's been building their own team, Nvidia and Vera-Rubin, God help Microsoft though). This does not bode well for RISC-V companies, who are just being used as a stepping stone. See Anthropic, who does currently license but is rumored to develop their own in-house talent [1].

"While" is doing some incredible heavy lifting. It is not enough to be able to run Ubuntu, as may be sufficient for embedded applications, but to also be fast. Thusly, there are many hardcoded software optimizations just for a CPU, let alone ARM or x86. For RISC-V? Good luck coding up every permutation of an extension that exists, and even if it's lumped as RVA23, good luck parsing through 100 different "performance optimization manuals" from 100 different companies.

10 years ago, when RISC-V was invented, the founders said 20 years. 10 years later, I say 30 years.
The nature of hardware as well, is that the competition (ARM) is not stationary as well. The reason for ARM's dominance now is the failure of Intel, and the strong-arming of Apple.
I have worked in and on RISC-V chips for a number of years, and while I am still a believer that it is the theoretical end state, my estimates just feel like they're getting longer and longer.
Not my area of expertise but what exactly is the difference between RISC-V and Power PC? Didn't Power-PC get a good run in the 90s and 2000s? Just wondering why there's renewed interest in RISC-like architectures when industry already had a good exploration of that area.
It is Chinese companies looking for ARM alternative that push this otherwise mediocre ISA.
It is possible that ARM based CPUs will start eating x86 market slowly. See snapdragon X2 and upcoming Nvidia CPU. Maybe in 10 years new computers will be ARM based and a lot of IoT will run on risc-5.

Meanwhile, wouldn't China be more heavily invested in Longsoon?

The V in RISC-V represents iteration of the ISA, over the last 46 years, most of which occurred in the US, mainly at Berkeley.
