In the long run we are all dead. So a “death sentence” far enough out is meaningless. Riscv killing arm is pretty distant.

They will all be replaced sooner or later.

At least, I did not choose the side of an ISA with global super strong IP locks like some...

There are much more toxic fan boys than some other fan boys...
