I can well imagine it being used on I/O sanitation, the AI 'thinking':
"nobody else cares to check if this string entry contains special characters, or overflows the length of a buffer, so why should I?", and then gets given Bobby Tables input strings.
All the same, an interesting project that is deserving of a pint/doctorate. I do hope someone does sensible unit testing on all the code it writes (although if it's just auto completing individual lines of code one would hope that there's a certain amount of user checking going on anyway - assuming a competent user, of course!).
