Comment on Utilons vs. Hedons

Like Douglas_Knight, I don't think current utilons are a useful unit.

Suppose your utility function behaves as you describe. If you play once (and win, with 90% probability), Omega will modify the universe in a way that all the concrete things you derive utility from will bring you twice as much utility, over the course of the infinite future. You'll live out your life with twice as much of all the things you value. So it makes sense to play this once, by the terms of your utility function.

You don't know, when you play your first game, whether or not you'll ever play again; your future includes both options. You can decide, for yourself, that you'll play once but never again. It's a free decision both now and later.

And now a second has passed and Omega is offering a second game. You remember your decision. But what place do decisions have in a utility function? You're free to choose to play again if you wish, and the logic for playing is the same as the first time around...

Now, you could bind yourself to your promise (after the first game). Maybe you have a way to hardwire your own decision procedure to force something like this. But how do you decide (in advance) after how many games to stop? Why one and not, say, ten?

OTOH, if you decide not to play at all - would you really forgo a one-time 90% chance of doubling your lifelong future utility? How about a 99.999% chance? The probability of death in any one round of the game can be made as small as you like, as long as it's finite and fixed for all future rounds. Is there no probability at which you'd take the risk for one round?
