risc-v isn't going to displace arm overnight. x86 still exists in the same markets it's always done well in despite over a decade of ARM trying to enter its markets. Raspberry Pi is doing the sane thing of delivering a good working product to its customers. It would have an interior product if it tried to do the same with risc-v.The fact there is no existing risc-v that comes close to competing with raspberry pi is evidence of this.
If you're in the industry and not using RISC-V, you're already late relative to your peers.
And you will be left behind should you drag.
We will sadly have to watch it happen to Raspberry Pi 5.
