For me it is Cellular Automata, and more precisely the Game of Life.
Imagine a giant Excel spreadsheet where the cells are randomly chosen to be either “alive” or “dead”. Each cell then follows a handful of simple rules.
For example, if a cell is “alive” but has less than 2 “alive” neighbors it “dies” by under-population. If the cell is “alive” and has more than three “alive” neighbors it “dies” from over-population, etc.
Then you sit back and just watch things play out. It turns out that these basic rules at the individual level lead to incredibly complex behaviors at the community level when you zoom out.
It kinda, sorta, maybe resembles… life.
There is colonization, reproduction, evolution, and sometimes even space flight!
Focusing on your points:
Controlling population - this is flawed completely, the lowest birth rates in the world are in the most affluent countries. In a lot of places it is below the replacement level of 2.1 births/woman. I think it is fine to accept the premise that hunger, disease etc are very bad things.
This is think is much more open to attack than point 2. Luxuries are of no moral significance, in my opinion is a flawed premise because it is both a “Straw Man” and a “Rhetorical Definition”.
In conclusion. You were correct to take issue with the presenter blindly accepting premises 2, 3 & 4. The way you tried to refute point 2 however was not great. Especially since point 2 is the only premise that we can say “is self evident”.
My points are more temporally distant then those of Singer, he is stating that helping now is better than building the ability to help much much more in the future.
