I agree this is only going to be possible for some universal Turing machines. Though if you are using a Turing machine to define a speed prior, this does seem like a desirable property.
Why is it a desirable property? I’m not seeing why it would be bad to choose a UTM that doesn’t have this property to define the speed prior for BoMAI, if that helps with safety. Please explain more?
I just mean: “universality” in the sense of a UTM isn’t a sufficient property when defining the speed prior, the analogous property of the UTM is something more like: “You can run an arbitrary Turing machine without too much slowdown.” Of course that’s not possible, but it seems like you still want to be as close to that as possible (for the same reasons that you wanted universality at all).
I agree that it would be fine to sacrifice this property if it was helpful for safety.
