I agree that at the low-end , at least in low-end ip-cores, RISC-V could do well. But in microcontrollers ? To be meaningful there, they will have to convince

I agree that at the low-end , at least in low-end ip-cores, RISC-V could do well. But in microcontrollers ? To be meaningful there, they will have to convince one of the big western guys to bet on them. But why would any of them care , enough to hurt their future relationship with ARM ,a significant risk ?
