Are people actually willing to date someone they otherwise wouldn't just for the free food?
Many, almost certainly. Whether they would ever admit to themselves that crude economic incentives could have a deciding influence at the margin is an entirely different question. They just need to feel different amounts of attraction without understanding why.
The last thread didn't fare too badly, I think; let's make it a monthly tradition. (Me, I'm more interested in thinking about real-world policies or philosophies, actual and possible, rather than AI design or physics, and I suspect that many fine, non-mind-killed folks reading LW also are - but might be ashamed to admit it!)

Oh, and I think that the "Personal is Political" stuff like gender relations, etc also belongs here.
