Hi Mike,
"$10,000,000 in 2100."
"Which looks an awful lot like inflation to me."
Yes, it probably looks like inflation, because the number is so high. But all those numbers are "year 2000 dollars". So they are adjusted for inflation to year 2000 dollars. The exact technical term is "Geary-Khamis" year 2000 dollars...also called year 2000 international dollars. They are essentially what numbers one would get if one adjusted for inflation that occurs between the year 2000 and the prediction years for all the countries of the world. Wikipedia's article on Geary-Khamis dollars is here:
