How rich are we?

Wrong, you are forgetting to factor in inflation over 10,000 years. (not to mention a different galaxy all together)

I did some math in another thread, based on the price of water in game, at 350isk per unit of water.

10isk per USD.

So at the rate of 1% per yer for 10,000years. The simplest version (and is wrong) comes out to about 1000USD per ISK. The more complex version which takes the value and compounds it every year for 10,000 years is way more than 1000USD per ISK… but I dont have that kind of time right now. Then there is an online calculator which I am hoping is WAY wrong… saying the inflation rate in 10,000years of .10USD at 1% rate of inflation per year…
$1,635,828,711,189,040,000,569,104,340,328,246,467,887,104.00!!!

So if that were true 1 ISK is worth $1,635,828,711,189,040,000,569,104,340,328,246,467,887,104.00

That is the estimated value of 1 ISK to USD.
