He begins by contrasting Monte Carlo simulations with simpler "static" retirement calculators and deterministic cash-flow projections, showing why modeling thousands of randomized market paths provides a more realistic stress test of retirement outcomes. From there, Jesse walks through the mechanics of Monte Carlo itself—from the concept of running massive numbers of random trials to the different ways simulations generate returns, including historical sampling, block bootstrapping, and statistical distributions like the familiar bell curve. But the heart of the episode focuses on interpretation: why headline numbers like "success rate" and "average wealth at death" can obscure the real story, how sequence-of-returns risk dominates retirement outcomes, and why most Monte Carlo tools fail to capture the dynamic decisions real retirees would make when markets turn against them.
