I don't think I missed the point; my point is that LLMs do something more complex and far more effective than memorise->regurgitate, and so the original analogy doesn't shed any light. This actor has read billions of plays and learned many of the underlying patterns, which allows him to come up with novel and (often) sensible responses when he is forced to improvise.
What kind of training data do you suppose contains an answer to "how to build a submarine out of spaghetti on Mars" ? What do you think memorization means?
