Another aspect of this is the relative simplicity of the toolchain. On my 10-year-old PC (Core i5 something or other) I can build a cross assembler and C compiler for the Amiga in around 21 seconds (vbcc, Vasm, Vlink). I can build the same on the Amiga itself in minutes (admittedly quite a lot of minutes!) rather than hours. Meanwhile, I read recently of a build of llvm on a RISC-V SoC taking well over 12 hours.
