There’s a good insight from this armchair psychoanalysis. The typical narcissist is technically capable of performing the whole pretend-to-care-for-game-theoretic-reasons behavior, provided that there is an incentive for them. However, if Elon genuinely believes himself to be Christ or Buddha or Roy, then his abilities don’t matter, because he will never have the incentive to deflate his beliefs and face his own limitations and mortality. In short, Elon’s attitude can’t be adjusted and his mental health will never improve.
Elon is an Expert Beginner: he has become proficient in executing the basics of the craft by sheer repetition, but failed to develop meaningful generalizations.
The original Expert Beginner concept was defined here in terms of the Dreyfus model, but I think it’s compatible with Lee’s model as well. In your wording of Lee’s model, one becomes an Expert Beginner when their intuition is specialized for seeing the thing; they have seen so many punches that now everything looks like a punch and must be treated like a punch, but don’t worry, I’m a punch expert, I’ve seen so many punches, I definitely know what to do when punches are involved.
