Imagine a calculator that crowdsources it's answers from the populace, how useful is that tool to the incompetent? How easily would the incompetent be able to tell it's bad?
That's what we're talking about: An autocomplete machine that has been trained on a million blog posts that contain some code, that maybe correct, incorrect, secure, insecure, outdated or uptodate and the machine can't tell the difference! It only knows what is and is not likely! So the more popular the wrong answer was replicated on the web, the more likely that's what you'll get!
