For the past few years my willpower has been steadily increasing. If it lasts and I use it to accomplish something noteworthy, I might write a post about it.
Anyway, what should a rational preference utilitarian with infinite willpower do? Assume that there are no negative effects (unhappiness, stress) with using this willpower, and that they can control their emotions at will.
Clearly they should work a lot more, not spend time on recreation (movies, TV, games), stand instead of sitting, etc..
What else? Should they listen to music? Should they keep their muscles flexed 24/7 ? What should they learn, where would they have the most relative advantage? How much time would be worth spending on social interaction?
I can figure out these things on my own, but those questions are important and good ideas are very valuable.
So any pleasure is considered luxury until death is eradicated, and finite willpower is the only apology that can justify not concentrating all one's efforts to fighting against death?
Imagine that aging was curable and you were essentially immortal - only there was an annual chance of 10^(-8) that you will die painful death by some accident. Would you forgo all trivial pleasures, if that spared you from the risk? In such a world, with present population of order 10^10, 100 people would still die painful deaths each year.
I would try to figure out how painful the deaths are and how trivial the pleasures are.
I don't think this world's an edge case yet though - decreasing pleasure now seems like it would increase long-term expected pleasure, e.g. by working more and using the money to make FAI more likely, or giving it to any effective charity.
