Well, to start off, the reason I picked 50% is the belief that most people, had they not been born, would have been replaced by someone else. Slightly <50% of the world could expect, on average, to be replaced by someone better. (specifically, 0.5*[the proportion that would be replaced])
The reason I chose >50% is that I believe that the population at present is larger than the optimum population. Iām not sure by how much, but I suspect the optimum for our current technology level would be less than 1/ā3rd of our current population.
Would you like me to explain why I believe the population is above optimum?

I would. Is it just the number, or is it the composition, or maybe the geographical distribution?
