I like this rebuttal, but you can go back and forth on both sides for eternity. Humans are selfish in nature. We birth (mostly) at our own convenience. The babe didn't ask to be a product of convenience, but it happened any way. Suffering is the cause of growth. If the world was to be erased of all suffering. Everyone would be objectively the same.

Friedrich Nietzsche was right. For those who may not know who Friedrich Nietzsche is, he was a German philosopher and author from 1844-1900. His primary philosophical foundation was Nihilism. However, he went on to create the philosophy of "Übermech" (also known as "overman" or "superman") which can be rougly defined as an idealized version of ones self. Übermech has an insatiable lust for power. Not in the normal way we see power presented through lust, but power in growth. Power in ones self. Power in your mind. To achieve this power, Nietzsche came up with an endless system to reach it. Self dissatisfaction> self improvement> self rediscovery> self dissatisfaction> self improvement.. etc etc. This is the circle of self-overcoming. If we have our own "why" in life, we'll get along just fine. The most significant of his teachings (which I will draw back to later) is his theory of suffering. Life is full of suffering, this is a lesson all of us learn. However, it's not a matter of "if", but "for what". In the words of Nietzsche, "The meaningless of suffering, not suffering itself, was the curse that layover mankind so far." Arguably, Nietzsche is one of the most significant philosophers history has gave us. Point being, his beliefs will never become quixotic. While humanity and science and economy and society and the minds evolve, I doubt there will be a time where we find ourselves without need for self improvement. To push that, I doubt there will be a time where we find ourselves without need for suffering. To suffer is to grow, and to grow is to suffer. Point of foreshadowing and explanation of his teachings, it is important that we as people, especially in the state of our world right now, reflect on our own growth. Are we dissatisfied with ourselves? Are we improving? Are we rediscovering? One can't rely heavily on an outside source to give them a sense of fulfillment, because we can only receive what we give ourselves. Thank you for your time.
