The odds of a hit versus a miss do not increase over time. The periods of a creator's career with the most hits also have the most misses. So maximizing quantity—taking more swings at the bat—has much higher payoff than trying to improve your batting average.

Simonton's 'constant-probability-of-success' model: quality ratio fluctuates randomly across a career.

Peak creative output varies sharply by field: lyric poetry, pure mathematics, and theoretical physics peak in the late 20s/early 30s with steep declines; novel writing, history, philosophy, medicine, and general scholarship peak in the late 40s/early 50s with little decline. These patterns are invariant across cultures and eras.

Precocity, longevity, and output rate are tightly linked. Those who start early also tend to end late and produce at extraordinary rates throughout—high producers produce highly, systematically, over time.

Beard's 1874 theory: creativity = enthusiasm × experience. Enthusiasm peaks early and declines; experience accumulates monotonically. Their equilibrium falls around 38–40, the most common age optimum. Poetry demands more enthusiasm; prose and scholarship demand more experience—hence the field-by-field peak differences.

Beyond an IQ threshold of about 120 (varying by field), intelligence becomes largely irrelevant in predicting individual differences in creativity. Raw smarts is not the variable that separates great producers from the rest.

The power law dominates creative fields: the top 10% produce ~50% of contributions, the bottom 50% produce only 15%, and the most productive contributor is typically ~100x more prolific than the least.

80/20 rule applied to creative output.

If you argue younger entrepreneurs have an edge, you also have to argue they'll die younger—poets, who peak earliest, have lifespans about six years shorter than prose writers across every literary tradition studied. Earlier peak, earlier exit.

Andreessen's two challenges: fit your opinion about age and entrepreneurship into Simonton's model, and decide—is entrepreneurship more like poetry/math/physics (late-20s peak) or like novel-writing/philosophy/medicine (late-40s peak)? And why?
