In principle it’s just “slimmer ARM”. RISC-V is also extremely dedicated to using memory mapped IO rather than older style IO x86_64 supports.

Think lots of registers, a fun zero register that is always zero, and memory mapped IO.

Maybe if people would stop living in places where natural disasters regularly happen without significantly adjusting their goddamn building strategies to create structures that not only survive, but also remain safe living spaces during these events for fucks sake.
