How do you handle anthropic scenarios (sleeping beauty, presumptuous philosopher, doomsday argument)?
Imagine the AI wants to determine what the would universe look like if it filled it with paperclips. It is superintelligent, so therefore it would have to have a very good reason. Since, in this hypothetical situation, there is a very good reason to fill the universe with paperclips, it would get lots of utility. Therefore, it is a good reason. It is actually quite difficult to prevent an AI from following this absurd-to-humans chain of reasoning without making the opposite mistake where it does not understand its own intelligence at all and mines itself for silicon.
Your premises preclude the possibility of meeting another AI, which could be very dangerous.

By defining the utility function in terms of the universe, rather than a subjective-experience path. Anthropics are a problem for humans because our utility functions are defined in terms of a "self" which is defined in a way that does not generalize well; for an AI, this would be a problem for us writing the utility function to give it, but not for the AI doing the optimization.

I am posting this is because I'm interested in self-modifying agent decision theory but I'm too lazy to read up on existing posts. I want to see a concise justification as to why a sophisticated decision theory would be needed for the implementation of an AGI. So I'll present a 'naive' decision theory, and I want to know why it is unsatisfactory.
The one condition in the naive decision theory is that the decision-maker is the only agent in the universe who is capable of self-modification. This will probably suffice for production of the first Artificial General Intelligence (since humans aren't actually all that good at self-modification.)
Suppose that our AGI has a probability model for predicting the 'state of the universe in time T (e.g. T= 10 billion years)' conditional on what it knows, and conditional on one decision it has to make. This one decision is how should it rewrite its code at time zero. We suppose it can rewrite its code instantly, and the code is limited to X bytes. So the AGI has to maximize utility at time T over all programs with X bytes. Supposing it can simulate its utility at the 'end state of the universe' conditional on which program it chooses, why can't it just choose the program with the highest utility? Implicit in our set-up is that the program it chooses may (and very likely) will have the capacity to self-modify again, but we're assuming that our AGI's probability model accounts for when and how it is likely to self-modify. Difficulties with infinite recursion loops should be avoidable if our AGI backtracks from the end of time.
Of course our AGI will need a probability model for predicting what a program for its behavior will do without having to simulate or even completely specify the program. To me, that seems like the hard part. If this is possible, I don't see why it's necessary to develop a specific theory for dealing with convoluted Newcomb-like problems, since the above seems to take care of those issues automatically.
