What's the issue with Solomonoff induction here?
"Higher-order-logic": reputedly down to concerns about uncomputability - which don't seem very interesting to me.
"Anthropic: I figure that can be dealt with in the same way as any other reference machine problem: by "conditioning" it by exposing it to the world.
"Cartesian": I think that's probably to do with this (from E.Y.):
AIXI devises a Cartesian model of a separated environmental theatre, rather than devising a model of a naturalistic reality that includes AIXI.
Fun stuff - but nothing specifically to do with Solomonoff induction. The papers on Orseau's Mortal Universal Agents page address this issue.
"I've come to agree that navigating the Singularity wisely is the most important thing humanity can do. I'm a researcher and I want to help. What do I work on?"
The Singularity Institute gets this question regularly, and we haven't published a clear answer to it anywhere. This is because it's an extremely difficult and complicated question. A large expenditure of limited resources is required to make a serious attempt at answering it. Nevertheless, it's an important question, so we'd like to work toward an answer.
A few preliminaries:
Next, a division of labor into "problem categories." There are many ways to categorize the open problems; some of them are probably more useful than the one I've chosen below.
The list of open problems below is very preliminary. I'm sure there are many problems I've forgotten, and many problems I'm unaware of. Probably all of the problems are stated relatively poorly: this is only a "first step" document. Certainly, all listed problems are described at an extremely "high" level, very far away (so far) from mathematical precision, and can be broken down into several and often dozens of subproblems.

My thanks for some notes written by Eliezer Yudkowsky, Carl Shulman, and Nick Bostrom, from which I've drawn.
