<p>Iran shouldn't have nukes, but starting a war—burning billions of dollars a day, killing kids and innocent civilians, and leveling bridges and universities—is objectively the worst possible way to prevent it.<p>The JCPOA under Obama actually did a solid job of constraining their nuclear development. That was the pragmatic approach, but Trump just unilaterally scrapped the deal. He doesn't have an actual strategy, maybe just "concepts of a plan".</p>

<p>I am not a native English speaker, I can do reading fine, but writing is a big trouble for me, especially formal writing and academic writing, AI can do help me writing better, of course I'll review what AI generated.(Above all are not written by AI obviously.)</p>

<p>How far is "near," really? Human civilization took tens of thousands of years just to discover a new continent, and the ocean back then was essentially as vast and impenetrable as space is today. If we ever actually develop near-lightspeed spacecraft, are we seriously assuming the first thing we'd do is build weapons capable of annihilating entire civilizations — and then actually use them? Oh my god, we already have those weapons, and the most likely target has always been ourselves.</p>

<p>Liu Cixin's Dark Forest theory is a pretty dumb take, honestly. Just look at Earth — different species don't constantly try to wipe each other out. Sure, it happens sometimes, but it's actually relatively rare, and a lot of the time extinction isn't even intentional. Like, a huge chunk of Native American deaths came from disease, not deliberate extermination.<p>At the end of the day, Liu Cixin is basically a social darwinist who's got a thing for authoritarianism, and it bleeds through pretty heavily into his work. Dude is massively overrated imo.</p>

<p>Sure, you are absolutely right. Even a sloppy study like this still had something useful than any anecdotes.</p>

<p>The study may well be flawed—small n, selection bias, lack of proper controls, sure. But can we please stop using personal anecdotes to dismiss scientific inquiry?<p>Arguments like 'well, it works for me,' or 'I took this med and recovered immediately,' or 'I saw X happen right after a vaccine' are not valid refutations. Science is frequently counter-intuitive and often contradicts our personal experience and gut instincts. That is precisely why we rely on the scientific method and statistical rigor—rather than individual perception—to establish evidence.</p>

<p>Dictators are absolutely terrified of the paper trail. This is the entire reason for existence of the Great Firewall. The CCP invests heavily in sanitizing imported literature and curating the information supply to maintain cognitive capture over the populace.<p>We are seeing parallel mechanics from the Trump/GOP camp: look at the library purges in conservative states and the push to co-opt moderation on platforms like TikTok. Access to the historical record isn't just a detail; it is the fundamental substrate of free speech.</p>

<p>"It is not possible to do the work of science without using a language that is filled with metaphors. Virtually the entire body of modern science is an attempt to explain phenomena that cannot be experienced directly by human beings, by reference to forces and processes that we can experience directly...<p>But there is a price to be paid. Metaphors can become confused with the things they are meant to symbolize, so that we treat the metaphor as the reality. We forget that it is an analogy and take it literally." 
-- The Triple Helix: Gene, Organism, and Environment by Richard Lewontin.<p>Here are something I generated with Gemini:<p>1. Sentience and Agency<p>The Horse: A horse is a living, sentient being with a survival instinct, emotions (fear, trust), and a will of its own. When a horse refuses to cross a river, it is often due to self-preservation or fear.
The AI: AI is a mathematical function minimizing error. It has no biological drive, no concept of death, and no feelings. If an AI "hallucinates" or fails, it isn't "spooked"; it is simply executing a probabilistic calculation that resulted in a low-quality output. It has no agency or intent.<p>2. Scalability and Replication<p>The Horse: A horse is a distinct physical unit. If you have one horse, you can only do one horse’s worth of work. You cannot click "copy" and suddenly have 10,000 horses.
The AI: Software is infinitely reproducible at near-zero marginal cost. A single AI model can be deployed to millions of users simultaneously. It can "gallop" in a million directions at once, something a biological entity can never do.<p>3. The Velocity of Evolution<p>The Horse: A horse today is biologically almost identical to a horse from 2,000 years ago. Their capabilities are capped by biology.
The AI: AI capabilities evolve at an exponential rate (Moore's Law and algorithmic efficiency). An AI model from three years ago is functionally obsolete compared to modern ones. A foal does not grow up to run 1,000 times faster than its parents, but a new AI model might be 1,000 times more efficient than its predecessor.<p>4. Contextual Understanding<p>The Horse: A horse understands its environment. It knows what a fence is, it knows what grass is, and it knows gravity exists.
The AI: Large Language Models (LLMs) do not truly "know" anything; they predict the next plausible token in a sequence. An AI can describe a fence perfectly, but it has no phenomenological understanding of what a fence is. It mimics understanding without possessing it.<p>5. Responsibility<p>The Horse: If a horse kicks a stranger, there is a distinct understanding that the animal has a mind of its own, though the owner is liable.
The AI: The question of liability with AI is far more complex. Is it the fault of the prompter (rider), the developer (breeder), or the training data (the lineage)? The "black box" nature of deep learning makes it difficult to know why the "horse" went off-road in a way that doesn't apply to animal psychology.</p>

Overall, recent economic evidence suggests that immigrant workers, on average, enhance the opportunities and incomes of native workers.</p>
