I am currently working my way through reading the responses to this essay, but I really liked your response and wanted to comment. I hope that is ok. You asked for "honest criticism" of people who are a lot like you; and while I realize you were asking Lukeprog I hope you don't mind if I throw my two cents in.
What I took from this essay is an idea I first encountered studying symbolic interactionism: That humans are animals with the unique capacity to act or to act. To act, in the sense that we, like all other living organisms can intentionally impact the territory we exist within. As a person I can run, fight, search for truth, etc. What makes humans unique is that in addition to this we hold the capacity to act, as in the sense of to pretend. In Tibetan Buddhism I believe this is called "shadow dancing," where you do something to mimic a form rather than become it. Luke has focused specifically in on the action of searching for truth. People can either genuinely search for truth, or they can for political reasons don the air of a truth seeker.
Now here comes your critique. The assumption people "who see it a lot like you" is that the former is in some way superior to the later. That one is necessary and the other is detrimental. it is important to genuinely seek truth, however, it is just as important to let it go and just actlike you are seeking truth. Not being able to do this is a problem of moderation. Probably more than 80% of humanity needs to learn how to act, how to be genuine in purpose. However, the elite who are already purpose driven need to learn how to balance serious action with social harmony (social harmony being what i think acting accomplishes).
I do not mean to pick a fight, but my honest criticism is you need to learn when to be irrational. What do you think?

What would it look like if someone was truly curious — if they actually wanted true beliefs? Not someone who wanted to feel like they sought the truth, or to feel their beliefs were justified. Not someone who wanted to signal a desire for true beliefs. No: someone who really wanted true beliefs. What would that look like?
A truly curious person would seek to understand the world as broadly and deeply as possible. They would study the humanities but especially math and the sciences. They would study logic, probability theory, argument, scientific method, and other core tools of truth-seeking. They would inquire into epistemology, the study of knowing. They would study artificial intelligence to learn the algorithms, the math, the laws of how an ideal agent would acquire true beliefs. They would study modern psychology and neuroscience to learn how their brain acquires beliefs, and how those processes depart from ideal truth-seeking processes. And they would study how to minimize their thinking errors.
They would practice truth-seeking skills as a musician practices playing her instrument. They would practice "debiasing" techniques for reducing common thinking errors. They would seek out contexts known to make truth-seeking more successful. They would ask others to help them on their journey. They would ask to be held accountable.
They would cultivate that burning itch to know. They would admit their ignorance but seek to destroy it.
They would be precise, not vague. They would be clear, not obscurantist.
They would not flinch away from experiences that might destroy their beliefs. They would train their emotions to fit the facts.
They would update their beliefs quickly. They would resist the human impulse to rationalize.
But even all this could merely be a signaling game to increase their status in a group that rewards the appearance of curiosity. Thus, the final test for genuine curiosity is behavioral change. You would find a genuinely curious person studying and learning. You would find them practicing the skills of truth-seeking. You wouldn't merely find them saying, "Okay, I'm updating my belief about that" — you would also find them making decisions consistent with their new belief and inconsistent with their former belief.
Every week I talk to people who say they are trying to figure out the truth about something. When I ask them a few questions about it, I often learn that they know almost nothing of logic, probability theory, argument, scientific method, epistemology, artificial intelligence, human cognitive science, or debiasing techniques. They do not regularly practice the skills of truth-seeking. They don't seem to say "oops" very often, and they change their behavior even less often. I conclude that they probably want to feel they are truth-seeking, or they want to signal a desire for truth-seeking, or they might even self-deceivingly "believe" that they place a high value on knowing the truth. But their actions show that they aren't trying very hard to have true beliefs.
Dare I say it? Few people look like they really want true beliefs.
