The other thing I see similar pattern for is Rust.
What are you talking about ?
Here a fan of ZFS/rust/RISC-V .... but also fan of ext4/C/ARM
It s like chocolate and beer. You may only like chocolate, or only beer or both or nothing, but they dont have the same purpose
If you love python, will you want to rewrite the linux kernel in python ? Maybe not because of the python interpreter, right ?
Programming language are tools, and if you want to write a program, you will try to choose the best tool that can help you achieve your goal, right ?
Linux kernel is already here ... doesnt make sens to rewrite it. (and C is perfect for OS writing)
But if you want to write a new tool from scratch where security is important, then why not considering rust ??
MIPS ISA wasn't open until recently. According to wikipedia, I quote "In December 2018, Wave Computing, the new owner[12] of the MIPS architecture (see MIPS Technologies), announced that MIPS ISA will be open-sourced in a program dubbed the MIPS Open initiative. "
Open and royal free ISA means cheaper processor, which is already a very good point. (the same way as linux is cheaper than windows).
But I dont think we will benefit now from this openness:
pretty sure that the first company which will build RISC-V processor wont make open hardware.
But it's a first step towards openness
Note: SPARC was not designed for low embedded devices. It requires more energy than ARM. There is no reason on wanting that in your mobile phone.
I think it's the same for POWER architecture.
But if you are a happy windows user, then you dont mind about open hardware/open source. Then I would agree: RISC-V wont be better for you.
ZFS is quite handy on big server. But not needed for laptop, and bad for embedded devices
