Their quality-of-life points combined with long-term-ism reminds me of that simcity build that maximized the population to absurd levels. If you get 'points' for each life, past and future, than maximizing the number of future life is the easiest way to maximize your high score. > Bostrom calculates that 10E29 potential lives are lost for every second that we fail to colonise the supercluster of galaxies containing t…

Without giving a derivation (which you can find easily on the web), the idea is that a gain of 1 USD that you get in 1 year has to be discounted with a factor of (1+i), where i is the (long-term stable) interest rate. For 3 years, the discount factor is, of course, (1+i)^3, i.e.
- a gain of 1 USD that materializes in 1 year is worth 1/(1+i) USD today
- a gain of 1 USD that materializes in 3 years is worth 1/(1+i)^3 USD today
Thus, including this discount factor for a future monetary flow (as in the PV calculation) makes gains that materialize in, say, 1000 years worth less today than those of the same monetary value that materialize (much) earlier.
