This is like me handing you a RISC-V iPhone (same price) and 30% of the apps work. Would you ever, ever, ever switch? No.
Sorry, Arm architecture skyrocketed to popularity because of an ultra long term strategy and a few rocket ship design wins like Android and the iPhone. I am afraid the door is shut.
Tizen might have been a good idea, but without a rocket ship to subsidize the improvements of the OS, it died. RISC-V boards are not different.
I am looking for a rocket ship, which is a new high volume use case which is not properly covered by the current set of solutions. Self driving cars? AI cameras? Robots? Nothing looks like it needs RISC-V in particular, none of it seems likely to produce iPhone scale novel designs that will eat the rest of the market out from Under arm.
