I'm not sure if anyone's noticed this, but how do you know that you're not a simulation of yourself inside Omega? If he is superintelligent, he would compute your decision by simulating you, and you and your simulation will be indisinguishable.

This is fairly obviously a PD against said simulation -- if you cooperate in PD, you should one-box.

I personally am not sure, although if I had to decide I'd probably one-box
