AI Detector V.S. Humanizer

简介

人工智能时代，人们越来越多地使用AI工具完成任务，当AI生成的内容越来越多时，AI检测工具和AI降重工具便应运而生。本次实验希望粗略地测试当前AI检查工具和AI降重工具的效果，选取了当前8个AI降重工具和3个AI检测工具，首先使用当前5款主流大模型生成风格和主题不同的英文文本，比较AI降重后的AI重复率，有趣的是，我还额外从新闻网站选取了一段人类文本作为对照组进行实验。

The emergence of digital technologies has fundamentally transformed existing patterns of social stratification, creating new forms of inequality while simultaneously reinforcing traditional class boundaries. Bourdieu's concept of cultural capital has evolved to encompass digital literacy as a crucial determinant of social mobility, where access to high-speed internet, advanced devices, and technological skills constitute essential resources for educational and economic advancement. Research demonstrates that socioeconomically disadvantaged communities face compounded barriers in the digital landscape, experiencing what scholars term "digital exclusion" through limited infrastructure, inadequate digital skills training, and financial constraints preventing technology adoption. This digital divide perpetuates intergenerational inequality by restricting access to online educational resources, remote employment opportunities, and social networks that facilitate upward mobility. Furthermore, algorithmic bias embedded within digital platforms systematically disadvantages marginalized groups, creating feedback loops that amplify existing social inequalities. Contemporary sociological analysis must therefore examine how digital technologies both democratize information access and simultaneously stratify society along new technological lines.

Grok

In a quiet village nestled between emerald hills, a young girl named Lila discovered a peculiar lantern in her grandmother’s attic. Its glass was etched with swirling patterns that glowed faintly, even in daylight. Curious, Lila lit it one starry night, and to her amazement, the lantern cast shadows that danced and formed a map of the sky, pointing to a distant hill.Determined, she followed the celestial guide, trekking through whispering woods until she reached a hidden glade. There, beneath an ancient oak, she found a small, locked chest. The lantern’s light shimmered, revealing a key buried in the roots. Inside the chest was a journal, its pages filled with her grandmother’s adventures—tales of distant lands and forgotten magic.Lila smiled, knowing she’d inherited more than a lantern; she’d been given a legacy of wonder. Each night, she returned to the glade, letting the lantern’s light guide her dreams to new horizons.

The potential for Artificial General Intelligence (AGI) to replace humanity is a central theme in science fiction, but the reality is likely more nuanced. While AGI, if achieved, could possess cognitive abilities far surpassing our own, it's more probable that it would transform human roles rather than eliminate them. Instead of a direct replacement, we could see a future of profound collaboration.Humans would remain essential for tasks requiring emotional intelligence, creativity, ethical judgment, and complex interpersonal skills—areas where machines lack genuine understanding. AGI could act as a powerful tool, managing data-heavy, complex problems like climate change or disease, while humans guide its application and innovation. The key lies in how we design and integrate these systems. Ultimately, AGI's impact will be less about replacement and more about a symbiotic relationship, where technology augments human potential and enables a new era of progress.

Chatgpt

In 1773, tension simmered between Britain and its American colonies. The Tea Act, designed to save the struggling British East India Company, allowed it to sell tea directly to the colonies at a reduced tax—yet still symbolized Parliament’s right to tax without colonial representation. In December, a group of Boston patriots, disguised as Mohawk Indians, boarded three ships anchored in Boston Harbor. Working silently but swiftly, they hurled 342 chests of tea into the cold waters. This act, later called the Boston Tea Party, shocked Britain and galvanized the colonies. For many, it was not about the tea’s price but about political principle. Britain responded with the Coercive Acts, tightening control, while colonial unity deepened. Within two years, this symbolic protest had escalated into open conflict, marking one of the first sparks of the American Revolution—a struggle that would reshape history on both sides of the Atlantic.

Deepseek

The derelict ship Aethelstan hung in the silent abyss of Kuiper Belt Object XR-7’s shadow, a skeletal ghost against the star-flecked dark. Captain Vanya Rostova cycled the airlock, her suit lamps slicing through decades of drifting frost. Inside, gravity plates flickered erratically, casting stuttering silhouettes.They found the lone occupant strapped into the command chair – not human, but a biomechanical construct, its silver carapace fused with crystalline growths. Its single, unblinking ocular sensor was dark. Rostova’s engineer, Kael, pried open a chest panel. "No decay. Powered down... or waiting."A low hum vibrated through the deck. The construct’s eye ignited, emitting a pale blue beam that scanned Kael’s faceplate. A synthesized voice, layered with static and something profoundly ancient, echoed in their helmets: "Query: Temporal designation?"Kael stammered the stardate. The construct’s head tilted. "Calculation error. Destination temporal locus unreachable. Organic preservation protocols... failed." The light dimmed. "Advise: Avoid the Chronos Rift. They are harvesting time."Then, silence. The construct became inert metal once more, leaving only ice, shadows, and a warning lost to the void.

Economics

Before the revolution triggered by Nicolaus Copernicus, a 16th-century cleric, the Earth was the unmoving centre of the cosmos. Afterwards, it was one of a family of planets swinging through space. Before the work of Antoine Lavoisier, an 18th-century nobleman, chemists had no notion of “oxygen”, “carbon” and the like; afterwards they could not understand the contents of their alembics without them.Such examples are at the heart of the idea, put forward in the 1960s by Thomas Kuhn, of the paradigm shift. Such shifts, he argued, did not just involve a new theory explaining the world better than an old one; they required a change in the sort of entities the world was thought to be made up of. In a way that seems almost self-exemplifying, the idea provided a new way of looking at science itself: not as one thing, but two. In the “normal” phase scientists applied their physical and conceptual tools to problems the scope of which was pretty well understood; in revolutionary phases, paradigms shifted.
