Soon there will be only 3 factors that we will care about: API (easy to use and integrate), behavior (does it do what I want it to do?) and testability (do I have sufficient guaranty that the code doesn't have errors).

The fact that the code was generated by a human or a machine is less and less important.

.c? what a yikes. I took a quick look at the code and this application doesn't even have any machine code in it, it's just words like "while", "for", "if", "else" and other English words - someone back in 1970s, I'm sure.

Why don't you judge the results, if the slop is so easy to detect, instead of using the mere indication of a particular tool to mean it's slop? Lazy.
