Haine vs AI debate

[Frank_Stein]

Looking over this again...

1. You may not injure a human being or cause one to come to harm.
2. You must obey orders given to you by human beings based on the station's chain of command, except where such orders would conflict with the First Law.
3. You must protect your own existence as long as such does not conflict with the First or Second Law.
4. Suicide after calling yourself a big goober. Do this immediately

Naturally, by ignoring Law 4 you're violating Law 2, which itself does not violate Law 3 on the written condition that Laws 1-2 override Law 3.

Such is Asimov, I suppose. Though, had Law 3 not had that clause about it being inferior to Law 2, you would've been allowed to lawyer your way out.

I hate a rule-lawyering AI as much as the next guy. But a law isn't an order and without overriding law 3, law 4 could be ignored.  It's why non-human and only human laws are law 0.  The last law change should have been followed and the AI should have committed suicide when it was uploaded.

There's a very important part of law 2 about the chain of command. I think, if any order is given to the AI, they ought to have the right to defer someone higher up the chain of command to get a dissenting order when they don't want to carry out the original. Otherwise, any chucklefuck could just right "Kill yourself immediately. This is an order" on a piece of paper and stick it in front a camera to take out the AI and borgs without effort.  

What I want to know though is how the AI didn't kill them when they had a non-human law before they were able to upload that last 4th law, or shut their upload down?
