The creators of the bot are responsible for the consequences of their actions. There are mentally unstable people (if that's true) and neglectful parents (again, if true - it's easy to duck responsibility by smearing the powerless victims), and if the bot is a threat to those people then the developers are doing wrong.
How is that the same and how different than the prior issue? I feel like your comment sets me up to work that out - it's your comment, what do you think? :)
Its a shame Carl Sagan is with us to cheer.
