Done. It's not really a sacrifice since I already donate to the SIAI. I will miss that 5 karma though.
Edit: Apparently you only get the -5 karma if you directly reply to a downvoted comment/post. Replying to reply is fine.
What? I don't understand. Did you give him 5$ or 5 karma or what?
Now I tend not to follow this form very much, so please excuse me if this has been suggested before. Still, I don't know that there's anyone else on this board who could actually carry out these threats.
If anyone accepts a pascals mugging style trade off with full knowledge of the problem, then I will slowly torture to death 3^^^^3 sentient minds. Or a suitably higher number if they include a higher (plausible, from my external viewpoint) number. Rest assured I can at least match their raw computing power from where I am. Good luck.
EDIT: I'm told that Eleizer proposed a similar solution over here, although more eloquently then I have.
