Thanks for asking this, it's super-important to understand it. If they're not infation-adjusted, then there's already been a (very slow) exponential reduction in the cost. I think they are inflation-adjusted. Here's an inflation-adjusted source that explicitly lets you pick FY2021 dollars as the reference: https://aerospace.csis.org/data/space-launch-to-low-earth-orbit-how-much-does-it-cost/ https://aerospace.csis.org/data/space-launch-to-low-earth-or... It puts the Saturn V at $5k USD/kg, the same as this article. What's interesting is that it shows a general downward trend a little more clearly than this one does, but the Falcon 9 and Falcon Heavy are still very shocking outliers.
