Yes, but look at how far we have come to understanding the universe in even the last century. Quantum theory, particle accelerators, etc. The stuff gets more and more complex to grasp. And we will probably not be able to figure it all out in our lifetime, but if we don’t have children and go extinct, then we cross out the chance of even getting there. Of course, we have to watch out not to completely screw up our planet on the way there. That’s why I believe in ecology, just not how it is portrayed by the activists.
The problem with overcrowding the Earth is probably gonna solve itself soon. It’s a typical S curve. There was an exponential growth, but now it’s fading and it’s much more possible that we could see the trend reverse in the coming decades. Anyway, I think we should really not pursue this issue within this topic. Let’s leave “not having kids for the sake of ecology” for another thread.
OK, I can’t resist myself to add one more thing. For some people, the goto thing is religion. To me, religion is bullshit. Or maybe, what contemporary religions have to offer is infantile pile of crap. In order to get excited about the future and life, I look to science and technology. I like to track the newest developments and ponder upon some theoretical explanations about the nature of the universe. I am definitely interested to know why and how are we here, I just find the answer given by religions totally disappointing.
