So it's interesting to note modern hardware is only 60x faster than Lisp machines when it should be 1000x. Weirdness of Lisp, turns out hardware isn't some random thing. And harder to compromise than modern stuff, by a huge amount, real actual security improvement.
Today one Lisp Machine CPU emulator written in assembler is 80 times faster than the original Lisp hardware. This could be made faster by a JIT compiler. Native code Lisp compilers for x86-64 or Apple's M1 are roughly 800 times faster than the original Lisp hardware (the third generation Ivory processor).
Wow! Really?! So the M1 really is faster in a non-gimmicky way? I could cut out this X86-64 assembly bullshit, at 800x I could be happy just with Lisp. Assembly all based on C by this point anyway...
