I had to re-read the title. I thought it said ‘Brain Filters’.

The RISC versus CISC argument took me back to the early nineties when I was studying computer architecture. From what I recall mainstream CISC chips started adopting some RISC ideas, but maybe I’m mistaken. I seem to have a memory of some of the past AMD chips (K5, was it) emulating the x86 instruction set in a RISC processor but maybe I’m wrong, it was so long ago!
