I never understood that Thanos reasoning, clearly he underestimates exponential growth. Killing 50% has you back where your started in 1-2 generations. How useless. Second, even though I don't think limiting population growth is a solution, but science is, Thanos should have calculated what the size of minimal gene pool for survival of a population was and went for that, much lower number that would have given him more bang for his (stupid) buck. In any case, I resent the idea that we should stop or limit procreation. All you others can do that, but my of spring will live among the stars and I will maximize my chances of it getting there. And don't even get started on selective procreation, it has been tried. Edit, perhaps this response is more towards the general sentiment in this thread, not op.

Killing 50% has you back where your started in 1-2 generations Thanos’s reasoning makes even less sense when you consider he removed 50% of all life; removing half the fish and half the birds at the same time as removing half the people leaves you no better off even immediately post-snap

  Also if Thanos had paid more attention in Graph theory class, he might have been able to do a better job of minimizing grief than just randomly killing half the vertices. He probably could have found sub graphs that were not very connected to other parts and eliminated them completely.

    DeathStar considered more moral than Thanos

    To accomplish his stated goal in the MCU (as opposed to the goal of impressing his girlfriend), he should have gone for maximum grief, along with preserving those islands of isolation since those islands are more likely to be the cultures that don’t engage in the fantasy of unlimited exponential growth.

  Well in the comics he was supposedly just trying to impress Death, a much more reasonable motivation.

And don't even get started on selective procreation, it has been tried. Personally, I'm not on the "the world needs fewer people" bandwagon either. While I'm not an expert, I've heard that the world population is expected to level off around 2100 at around 10.9 billion, not that much higher than the current 7.8 billion. So we will never get to some Malthusian point where there isn't enough food to go around. Meanwhile, at a small scale, adding one person does marginally increase the cost of feeding everyone and marginally increase pollution, but that person will also contribute to society and the economy. When humanity someday goes to space, perhaps the population will start growing again, but if so, it will be precisely because there will be more resources for them. In other words, the effect on society of having kids seems to be pretty neutral in practice. Given that, I have no reason to oppose your desire to spread your genes, assuming that's what you meant. Personally, I don't care whether the ones living among the stars have my genes or somebody else's, but that's just me. I do think it would be nice to maximize the chance of humanity as a whole someday living among the stars, but increasing the population would not necessarily help with that.

> I never understood that Thanos reasoning, clearly he underestimates exponential growth. This is a common thread in discussions of overpopulation. One particularly egregious example I've seen is where people object to immortality[1] based on overpopulation concerns. As in this case, killing literally everyone (after they reproduce) only gives you a couple of generations of breathing room. Exponential growth is really really unintuitive. [1] I didn't say it was a particularly realistic discussion

Just remember that rabbits kill themselves through starvation long before they invent boats to get to the next island full of resources to consume. Controlling population growth is a far preferable option to mass murder either by actively killing people Thanos-style, or passively killing people Malthus-denier style.
