Actually, I wouldn't mind a tool for computer-aided legislation. At least 'round here, it's not too uncommon for laws to be passed even though they are poorly worded, ambiguous, unenforceable, or in direct conflict with other standing laws. I'm not saying have the bot write the laws, but I wouldn't mind a bot that can spot things like "you can't ban x, because it would conflict with EU free trade agreements" or "if you set y as the penalty for this crime, it makes it punished worse than this other crime which is a lot more serious" or "taken literally, this would ban swimming, are you sure?"
Of course, claims that the bot has a (liberal|conservative) bias would pop up almost immediately. Eh, nevermind.
