Hi Bruno

In my discussions of intelligence, I define intelligence
as the ability to (fairly freely) make one's own choices.


That implies through the word "own" that there is a
fixed identity, the chooser


A picture of this might be the triad:

choice A                 choice B
      \                    /
         The chooser,
     which must have
       a fixed identity


Dear Roger and Bruno,

It seems to me that we automatically get a 'fixed identity' when we consider each observer's 1p to be defined by a bundle or sheaf of an infinite number of computations. The chooser of A and of B is one and the same if and only if the computational bundle that make the choice of A also make the choice of B. What you are considering is just an example of my definition of reality. ;-)

Is there a chooser in comp ? Meaning a fixed identity ?

Yes. But we might have a problem to know who it is.

The problem disappears if multiple observers have a way to 'locate' an incarnation of the computational bundle.

Does a Turing machine have a fixed identity to make such choices
(or do anything)?

Perhaps, but the she can become amnesic and forget who she is, and she might be deluded on many things, but she can also remember, but I don't know how much.

A forgetful observer is the one that we see in the case of a Boltzmann brain.
