In essence you are complaining about what is, the state we find people in who post on Anadtech OT. You want them to grow up. You are saying they don't satisfy a need you have. You define it as a desire for more intellignece. If I've got this right then let us look at some possible answers:
In the first place there is no point in complaining about what is. What is, is. That's the remarkable thing about what is. It's one thing to critique what is, to analyze it, to try to understand it, but to complain about it is to imply a failure in your personal understanding. Complaining changes nothing. It is an emotional response, and if I may say so, not a very intelligent one, as I hope you can now glimpse.
The problem, of course is, that if people are immature, young, unsophisticated, undeveloped, shallow, or stupid and unintelligent as you wish to claim, telling them that will not change them. How much maturity will you find in a nursery of gifted kids. Not much. So we aren't talking about intelligence here, but more like what I described in the first part of the sentence. Well you can't put an old head on young sholders, as they say and have been saying probably for thousands of years. You can't squeeze blood from a turnip. You don't build castles on sand.
So we come to the question of why you complain. I described it as having a need that isn't being met. You want something you aren't getting. What could that be, intelligent mature and sophisticated conversation? Why do you need this. What we need is air, food, shelter, water, etc. So you want it, actually. What is that want? What lack are you experiencing that tells you you need to fill it? Normally people don't look at themselves, ask themselves why the feel what they feel. Maybe they lack the maturity to do so. But they don't. And because we are being serious for a minute, trying to look into things with some intelligence, can we conclude that what we want is based on feelings we don't normally understand. Well if so, how are we going to understand what we don't understand. You can't put an insightful head on naive sholders. Anybody who knows will be speaking an incomprehensible language, will be able, essentially, to see in the dark.

It could be that what lies there in the dark, or more exactly why it is dark there is because what we could see isn't flattering.
Suppose, just for a moment that what we want is to satisfy our egos, our idealized self images. I think of myself as an intelligent and sophisitcated person, at least I would like to, but I'm surrounded by morons.

I long to have my desired self image fulfilled. I feel a pain that it is not. I complain. But is my ego desire arises from illusion, if my ego is an artificial construct designed to cover up a need I feel isn't being met and that need is itself the illusion then I become like a vacuum sucking vacuum. What if I'm upside down. What if I'm really an endless cornucopia, a limitless resource of that good old loving feeling. What if I'm mana from heaven.
Well in tha case what I might want to do is to 'shine on you crazy diamond'. In a case like that there might not be much else to do but give, to live, to exemplify something in the hope that somebody somewhere catches the disease.
Isla, how I love Whinnie.
