Meanwhile, somebody put 8192 arm cores on a chip and ran a risc-v emulator on top of that which emulated a 6502 which then emulated a 288 core xeon and it used 0.01% of the power and outperformed the Intel chip in every other metric 10:1, probably.
Only slightly related, but six years ago I was able to run 400 ZX Spectrum (Z80) emulator instances simultaneously on an AWS graphics workstation.
You know, a link would be great for this comment.
