RISC-V has found a niche in anything embedded that needs some decent performance, especially in storage and networking. With a little imagination you can see some products there merge with other functionalities and take over larger markets, e.g. a NAS product line incorporating smart home and smart speaker functionality, evolving into 'home box' systems.
I would be willing to overpay a fair bit for NAS and other network equipment running open source hardware and software from the ground up. That’s an application of RISC-V I truly believe in.
Still, looking at the struggle ARM has had in spite of its ubiquity in even now fairly high performance devices, I will probably remain skeptical, for now, about such a transition. We have ARM NASes, routers, even competent servers! And yet... no real desktop towers. (At least a few exist, but I am thusfar unable to find any that are sold B2C retail or even second hand that look enticing.)
