Appreciate your response.
I am a bit clearer now, and obviously a lot still remains to be done. Thanks for bringing some clarity to: model, uncertainty and undecidability.
Is the computational irreducibility similar to irreducible representation in group theory? Or is it so that the problem is not amenable to computation (at least with current information)?
Penrose talks about computability of mind (processes), is it irreducible if so in capacity of today's machines or because we can not yet reduce it to computation?

The answer to your question is "nobody knows." It is not even a widely
accepted problem.

John Sowa talks sometimes about an "infinite lattice of theories", but
it is not clear how this would work.

It is to John's credit that he is one of the very few people who
consistently push this problem.

As should be clear from my posts here, I believe you can model
physical processes, or word associations, computationally, working
directly with observations, and because of undecidability get the
effect of uncertainty in associated concepts/theories.

Briefly that you model properties of interest to you by directly
generalizing word associations or observations, and get something like
uncertainty in associated concepts, because of
undecidability/computational irreducibility.
