What's the difference between a static AI and a dynamic AI? I recently watched a YouTube video (sorry, can't remember the link) where (a very talented) someone created what they called a "static AI".

Somewhere in the video they said something along the lines of:


  "this is a static AI, it's very simple and not dynamic at all"


What does this mean? What's the difference between a static AI and a dynamic AI?
My sense is they're probably talking about the difference between symbolic AI (aka GOFAI)  and learning algorithms.

GOFAI typically uses heuristics, which are static—essentially fixed rules governing decision making.

Statistical AI, aka Machine Learning, is dynamic and can analyze and evaluate the environment to form its own decision rules.  

Sometimes a trained NN that is no longer learning is said to have created it's own heuristics.
