In every field where competence can be objectively measured, experience does not endlessly correlate with competence. There's always a growth phase but then there's a bell curve of age vs competence, that reaches a peak and then there's a constant decline from there. So for instance chess is primarily a mental game, yet the decline comes as early as one's mid thirties for world class players.

I'm fully willing to accept that for a field where scenarios are fuzzier and intuition more important, it may well be that peak on the bell curve comes somewhat later. But I think it's essentially inconceivable that one is near, or even remotely near, their peak, in their 80s, in anything.

A bell curve tracks the distribution of a single random variable. You're mixing statistical metaphors.
