The problem is not AI code, but not knowing about system architecture or intent

    I some very real way this has been true for a very long time. Does anyone know how a AMD Ryzen processor works? I mean does anyone understand in any detail how it works from machine code down to the transistors?

    Does anyone single person understand what’s happening when compiling a large C++ code base? Meaning, can anyone track the basket cast C++ language constructs down to the Clang IR to the optimized machine instructions? From there can any one person follow those machine instructions all the way through to the actual registers etc to actually running the code?
