I've seen many great men and women throughout history who contributed to humanity, no doubt they are amazing and they build the world as we know it and will certainly achieve more than any of us here ever will. But I can't help but to witness outside of them the onslaught of stupidity across the world. Most of such people don't do anything really useful in life, they just eat up the harvest brought by the former's hard work and intellectual prowess, leaving them offspring to continue the deed later on. And the brightest ones, who were an alarmingly small portion of the populace, will continue to bear their burden. In the end, there will always be a million idiots for a genius out there. And how are we going to change that? We probably can't and won't, or maybe I'm just projecting.
Sounds like eugenics narrative, but that's the thing, everyone is important, we are nuts and bolts for the machine we call civilization, what you think of those "eaters" is superficial, because you see, you don't need to be a great mind to contribute something to society, you see the majority needs the minority, and the minority needs the majority, the workers are the one who build the machine, industrial plants, farming, transportation, the higher minds preffer to sit in their couch all day thinking, but without the lower minds, their medium would be impossible, because they personally can't grow the crops, drive the cars, or give the funds to said projects to be a reality, just tell me, does Elon Musk or any of his scientists has ever grabbed a pickaxe in his precious diamond mines? They don't, you see, everyone has a reason, and is a highly important member to society, because humanity is a highly social being, we crave for love, for purpose, for actions, no one wants to live like a parasite (besides a very few exceptions), so they act, our work in this world is always try to make a better living condition for us and those who needs it.
Also "will certainly achieve more than us here ever will" why does that really matters tho? Are you implying that the only purpose of humanity is to contribute to the colony and just die? If that's the case, that's a worrying mindset partner, we are not ants, being a genius doesn't means you are gonna be better than everyone else, in fact that does not define your happiness at all, most geniuses had ended up with miserable lifes, Oppenheimer, Alan Turing, Archimedes, Marie Curie, fucking hawkins had the mobility of a pickle, he was, indeed, pickle steve, not counting the numerous minds that went into oblivion, or never rocketed in the first place, i've been met hobos with more intelligence than the so called "geniuses" while i had to see spoiled kids living better lifes than any of them, just because they were born, is an unfair world, and everything is an spectrum, at the end what matters is what you want in this life, if you think contribute to something is gonna fulfill your deepest desires, that your dreams are gonna become a reality, go ahead, but never dismiss others by not being paired at your same level.
Not mentioning that there are a lot of kinds of intelligence, not only logical, you can be a genius in so many of them, humans are not all a collective mind, we all are different, and we live under different context, some others are dumb in certain things, and some others are completely geniuses in other tasks, if we are all logical, everyone would be an engineer, if we are all creative, we are all gonna be artists, we can't just be a mass produced da vinci, IQ is just a mere number and will never decide your success or failures.
