RISC-V is probably no different than ARM at it's core. Also, both of them are RISC ISAs.

Right now, you are far more likely to use RISC-V and not know it than to knowingly interact with RISC-V directly. For example, since about 2015, Nvidia has used RISC-V as an onboard controller for their GPUs.

Both ARM and RISC-V are Reduced Instruction Set Compute (RISC) instead of Complex Instruction Set Compute (CISC aka x86) architectures. So it's more about the tooling that makes one better than the other. And like all open source, the tooling will be better over time as people and organizations recognize they get more back out of contributing to open systems.

I'm not native English speaker but I think that the current and near situation in local Carrefour would be influenced by “abandoned” rather than “abandoning”.
