Impossible. For one, big game player like Apple already hedge into ARM. Once you make a decision like that you don't change for ten years at least. The ARM transition is going well lots of developers already prepare native arm support. As a developer you already developing for X86 and ARM now. No way you have the resources to develop for RISC-V in addition.

Those that argue risc5 will take over because open source and free, see the argument for Linux. Open and free is not what market wants.
