    In addition to that, according to Reuters NVIDIA and AMD have plans to launch consumer ARM platforms for PC until 2025. So, assuming that's true and considering Apple ecosystem, ARM64 is by far more likely to be market taking ISA than RISC-V.

    RISC-V is inevitable.

    RISC-V enables the best processors.

    RISC-V is rapidly growing the strongest ecosystem.

    Not doubting it. Just trying to keep up.
    just a different architecture but a relatively open one. we are seeing a lot of innovation on the riscv front that we simply havent seen on arm due to it's open nature, and thanks to that we should be seeing some wicked good products coming in the future. it also has a lot of benefits for military and governmental applications since countries can more easily fab their own computing devices and actually keep the technology in house. (This has been an issue that has plagued America since they keep getting counterfit chips, this costs money and is a potential security liability).

    ofc diehard security enthusiasts could potentially design and assuming you happen to somehow know a fab is trust worthy, make your own chips

    Well, considering Tenstorrent and Jim Keller are jumping on the RISC-V bandwagon, I've got to imagine we'll see some pretty awesome chips before long. With companies that fully design their own chips still having to pay ARM for licensing the instruction set, there's going to be a point in time where it just isn't cost effective. I'm pretty sure the instruction decoder is a fairly small part of the overall CPU design, so switching from ARM to RISC-V while maintaining a significant part of their existing IP might be more cost effective once the software ecosystem is fully established.

    Phoronix: Linux RISC-V Preparing For Real-Time Kernel Support (PREEMPT_RT)

    As we approach the end of 2023, sadly, the real-time kernel "PREEMPT_RT" support still hasn't been mainlined... The main blocker pending is still the ongoing work around non-blocking consoles / threaded console handling to then allow the few dozen remaining out-of-tree RT kernel patches to be merged. The good news is that when the PREEMPT_RT support is ready for mainline, it looks like the RISC-V architecture support will also be real-time friendly too...
