The world is going to shit right now and having children means risking them having to be the ones to suffer the consequences of our past generations actions. "Humanity always survives" is a dumb argument too. "Surviving" doesn't equate to a good life. Surviving can, and usually does, mean having to through a lot of trauma and hardships in order to stay alive. With the worsening state of world, from climate change, the growing wealth gap, late-stage capitalism, growing political divides, etc, things aren't likely going to get better anytime soon. A growing number of people are opting to not have kids as a result of how bleak the future looks right now.
Having children also has nothing to do with believing that people can change or that we can improve our lives. Studying beforehand isn't going to be enough to do anything. Raising and teaching children in practice is very different from raising and teaching them in theory. Even with knowledge on child cognitive development, that usually isn't enough. Children require a lot of patience and understanding, and I mean A LOT, and how a child sees the world and processes things can differ greatly from child to child. I've seen plenty of cases of people who've done all the same shit that you are planning to do, only to raise children who end up becoming dysfunctional traumatized adults. Having children in order to prove something, whether that be to yourself or others, usually doesn't end very well. Children aren't things for you to play around with in order to prove your point or to help with you trauma. Just because you believe that you are capable of something doesn't mean you are. Most parents think that they are emotionally and financially capable of raising children and look at how most these people treat them. Do you know how nany cases there are of people losing their finanical stability due to things completely out of their control? Do you know how many parents there who thought they were emotionally capable of handling children until they had their own? You are already thinking of them as little play things you can use to provide yourself with happiness and prove a point, rather than as actual human beings.
"What if they are the happiest people on earth"? Ignoring how it would be extremely difficult to even evaluate that, what are the chances that you'll actually raise someone who will grow up to be one of the happiest people on earth? You are more likely going to end up raising another unhappy dysfunctional person, like what most parents do, than you are to raise one of the happiest most well-adjusted people to ever exist.
Even if you were somehow the greatest parent out there, you still cannot control the shit that goes on around the world. You can't garauntee that you won't accidently mess up in some way and traumatize them for the rest of their life, you can't stop them from potentially being harmed by others, you can't fix all the societal issues going on right now, you can't stop them from having to deal with the pressure that comes from the expectations and responsibilities that society pushes on to them, you cannot garuauntee that they won't end up inherenting any potential medical or pyschological issues, etc. Hell, there are people on here who have had good lives and are incredibly fortunate but still want to ctb. I still want to ctb and I have good parents, a good family, a good life, no prior trauma, no medical issues, and no mental illnesses. I've wanted to die since I was 8.
I don't consider myself an antinatalist, I'm not making this post to insult you or make you feel bad, but deciding to have childten is an inherently selfish decision and even your reasoning for it just reflects your own selfish desires. You seem to want children to prove something to yourself. You want to have them because you think you'd like it. You are no different from the selfish people you look down on.
