Via analogy to computer programming, I can assent to what you
   said there.

   Predictability vs deterministic. I can have a fixed array of
   values. I can also program a basic AI that has predictive
   capabilities, based on algorithms.

   There is no guarantee that any of those algorithms I program
   will be able to predict the values in the predetermined array.

   So, with that, I agree with your statement that predictability
   is not suggested by deterministic values.
