It feels very relevant that you’re flagrantly violating the “Don’t Make Things Worse” principle.
By triggering the bomb, you’re making things worse from your current perspective, but making things better from the perspective of earlier you. Doesn’t that seem strange and deserving of an explanation? The explanation from a UDT perspective is that by updating upon observing the bomb, you actually changed your utility function. You used to care about both the possible worlds where you end up seeing a bomb in the box, and the worlds where you don’t. After updating, you think you’re either a simulation within Omega’s prediction so your action has no effect on yourself or you’re in the world with a real bomb, and you no longer care about the version of you in the world with a million dollars in the box, and this accounts for the conflict/inconsistency.
Giving the human tendency to change our (UDT-)utility functions by updating, it’s not clear what to do (or what is right), and I think this reduces UDT’s intuitive appeal and makes it less of a slam-dunk over CDT/EDT. But it seems to me that it takes switching to the UDT perspective to even understand the nature of the problem. (Quite possibly this isn’t adequately explained in MIRI’s decision theory papers.)
