I should have been more clear. I put at the
(3-) bottom arithmetical truth. It just means
I believe sentence like "2+2=4", Fermat theorem,
Goldbach conjecture, or like "the machine with
Goedel number 42" does not stop on 24", etc.
are true or false independently of my ability
to prove them or not. 

I am trying to show you (in the UDA threads)
that physics is a 1-phenomenon and it will appear
that 1-phenomenon truly lacks bottom.

There are 3-bottoms, no 1-bottoms. This is
not unrelated to incompleteness phenomena
but the UDA illustrates that quite well.
Well, let us hope.

Also, how would a friendly entity manages
bottom-up links between a universal automata
and the "observers" it generates?
