Bayesian net worth calculator says $10 from a normal person equals $105M for a billionaire

An AI-circle spat over whether billionaires like Elon Musk are stingy turned into an interesting utility-math thread. AaronBergman18 argued from revealed preferences in insurance spending that $450 from someone with $100k net worth and $100k/year is worth at least $4.5B to someone with $1T, using the smallest reasonable estimate of the diminishing-returns parameter. He also noted his tool stops reporting numbers past a point, so he had to compute at $10 and scale up.
Counterpart panickssery shared a marginal-utility calculator screenshot: with η=1.25, $10 from a person earning $100k/year with $100k net worth "feels like" $105.4 million to a trillionaire (10.5M× more) — so in absolute utility loss, $10 from a normal person far exceeds the linear equivalent for Elon. Panickssery admitted he didn't do the math himself.
