What is fully human written and how are you as a human(I assume) able to distinguish between what is laboriously typed and what is generated, here lets try this exercise and see if you can spot any difference Here is a code I have typed by hand

"smash":
        push    rbp
        mov     rbp, rsp
        call    "smash"
        pop     rbp
        ret

and here is machine generated code with the prompt, the slop machine used here is a compiler

GCC take this C code void smash(){smash();} and make it executable and here is the output

"smash":
        push    rbp
        mov     rbp, rsp
        call    "smash"
        nop
        pop     rbp
        ret
