That's the one. I sent it to five of the world's leading decision theorists. Those who I heard back from clearly hadn't grasped the main idea. Given the people involved, I think this indicates that the paper isn't a sufficiently clear statement.
As a professional philosopher who's interested in some of the issues discussed in this forum, I think it's perfectly healthy for people here to mostly ignore professional philosophy, for reasons given here. But I'm interested in the reverse direction: if good ideas are being had here, I'd like professional philosophy to benefit from them. So I'd be grateful if someone could compile a list of significant contributions made here that would be useful to professional philosophers, with links to sources.
(The two main contributions that I'm aware of are ideas about friendly AI and timeless/updateless decision theory. I'm sure there are more, though. Incidentally I've tried to get very smart colleagues in decision theory to take the TDT/UDT material seriously, but the lack of a really clear statement of these ideas seems to get in the way.)
It's not Quinean naturalism. It's logical empiricism with a computational twist. I don't suggest that everyone go out and read Carnap, though. One way that philosophy makes progress is when people work in relative isolation, figuring out the consequences of assumptions rather than arguing about them. The isolation usually leads to mistakes and reinventions, but it also leads to new ideas. Premature engagement can minimize all three.
