What comes after the AI crash? (disconnect.blog)
This article by Paris Marx argues that while the current AI hype cycle, fueled by tools like ChatGPT, might be heading toward a market correction, the real concern lies in the aftermath. Marx cautions against repeating the mistakes of past tech bubbles where societal harms lingered even as public and investor attention moved on. He emphasizes the need to proactively address the potential negative consequences of AI, particularly its use in exacerbating existing inequalities and its environmental impact through data center expansion.
Key Points
1. The AI Bubble is Real, But Not the Whole Story:
Explanation: Marx acknowledges the overvaluation of AI and the inevitability of a market correction. However, he stresses that the focus should be on the long-term implications of AI beyond the immediate financial fallout.
Quote: "There’s no question tech stocks are overvalued and that part of that comes from the hype behind generative AI. The question isn’t whether there will be a market correction, but when it will happen and how deep the decline will be."
Why it matters: This point sets the stage for a deeper analysis of AI's impact, urging readers to look beyond the surface level of market fluctuations.
2. The Dangers of Entrenched Harms:
Explanation: Marx parallels previous tech bubbles like crypto and the gig economy, where initial hype faded, but harmful practices persisted. He warns against allowing AI to follow the same pattern.
Quote: "We can’t allow that same cycle of entrenchment to play out with generative AI. Chatbots and image generators may have more tangible use cases than crypto, but that also means they can be used against people in many more ways once the hype fades."
Why it matters: This point highlights the risk of societal normalization of AI's negative aspects if left unchecked after the initial excitement subsides.
3. Exacerbating Existing Inequalities:
Explanation: Marx argues that despite AI's promises, its implementation often reinforces existing societal biases and harms vulnerable communities, citing examples like biased algorithms in welfare and immigration systems.
Quote: "There are already countless examples of algorithmic systems have been used to harm welfare recipients, childcare benefit applicants, immigrants, and other vulnerable groups. We risk a repetition, if not an intensification, of those harmful outcomes."
Why it matters: This point emphasizes the ethical imperative to address AI's potential to perpetuate and even worsen existing social injustices.
4. The Environmental Cost of Data Centers:
Explanation: Marx highlights the often-overlooked environmental impact of AI, particularly the massive energy and water consumption of data centers required to power these technologies.
Quote: "Data center infrastructure is fueling opposition the world over for its water and energy demands, but the cloud giants are pushing forward with hundreds of billions of dollars in investment allocated to ramp up construction."
Why it matters: This point emphasizes the need to consider AI development's sustainability and environmental consequences, especially as its reliance on resource-intensive infrastructure grows.
5. The Need for Proactive Action:
Explanation: Marx concludes by urging continuous scrutiny and proactive measures to mitigate AI's potential harms, even after the hype dies down. He emphasizes the importance of challenging harmful implementations and holding stakeholders accountable.
Quote: "They’ll need to be challenged, even after the attention moves on to the next source of tech hype."
Why it matters: This point serves as a call to action, urging readers to engage in ongoing critical assessment and advocacy to ensure AI's development aligns with ethical and societal well-being.
In essence, the article is a cautionary tale about the allure of technological hype cycles. It reminds us that the true measure of progress lies not just in technological advancement but in its responsible and equitable implementation for the benefit of all.
Religion 2.0 - by Jurgen Gravestein (substack.com)
This article by Jurgen Gravestein explores the intriguing intersection of artificial intelligence and religion, arguing that in an increasingly secular world, AI is uniquely positioned to fill the void left by declining religious belief. Gravestein highlights the almost religious fervor surrounding AGI (artificial general intelligence) within the tech community and examines how AI, perceived as possessing god-like powers, might become a new form of religion for a disenchanted world.
Key Points
1. The Religious Fervor Surrounding AGI:
Explanation: Gravestein shares an anecdote about OpenAI, a leading AI company. Executives engage in rituals like chanting and burning effigies, demonstrating an almost religious zeal for achieving AGI.
Quote: "Chanting, wooden effigy's, fire rituals — these are not the first things that come to mind when you think of a technology company. When did AI and religiosity become so intertwined?"
Why it matters: This point establishes the almost faith-based belief in AGI's inevitability and transformative power that pervades the tech industry. It sets the stage for exploring the deeper connection between AI and religion.
2. Filling the Void of a Secular World:
Explanation: Gravestein acknowledges the decline of traditional religion in the face of scientific advancement, citing Nietzsche's concept of the "death of God" and the resulting void of meaning. He posits that AI, with its seemingly magical capabilities, is poised to fill this void.
Quote: "Historically, people have turned to the supernatural for that which they do not understand or control. But in today’s day and age, AI is able to — and here we circle back to our friend Nietzsche — fill that void, this religion-shaped hole left behind by God."
Why it matters: This point highlights the human need for meaning-making systems and suggests that AI, with its aura of superhuman intelligence, could fulfill a similar role to traditional religion in providing answers and comfort.
3. AI as a New Form of Religion:
Explanation: Gravestein argues that AI's ability to perform tasks beyond human comprehension and our tendency to anthropomorphize technology lead to its association with god-like powers. He suggests that this, combined with the decline of traditional religion, paves the way for AI to become "Religion 2.0."
Quote: "There’s research that suggests people associate robots and AI with gods more than with humans, and despite what common wisdom tells us, more often than not, people prefer algorithms over human experts."
Why it matters: This point underscores the potential for AI to evolve beyond mere technology and become an object of reverence and faith, shaping our values and worldview much like traditional religions have done for centuries.
4. Historical Precedents of Artificial Life:
Explanation: Gravestein points to historical examples like medieval automata and Jewish golems, demonstrating the desire to create artificial life with intelligence and agency is not new. He suggests that AI represents a continuation of this ancient human fascination.
Quote: "Just like automata represented early attempts to replicate human cognition through mechanical or spiritual means, so does AI."
Why it matters: This point emphasizes the deep historical and cultural roots of our current fascination with AI, suggesting that it taps into a fundamental human desire to understand and even transcend our limitations.
5. The Promise and Peril of "Religion 2.0":
Explanation: Gravestein concludes by highlighting the potential benefits of AI, such as solving complex problems and improving human lives. However, he also cautions against blindly placing faith in technology, reminding us that AI is a tool that can be used for good or ill.
Quote: "End scarcity, free us from the bonds of labor, immortality by uploading our consciousness to the cloud and ascend into the infinite universe — if that doesn’t sound like a techno-version of Heaven, I don’t know what does. It’s New Testament, but upgraded. Religion 2.0."
Why it matters: This point reminds us that while AI holds immense promise, it's crucial to approach its development and implementation with critical thinking and ethical considerations, ensuring it serves humanity rather than becoming an object of blind faith or a tool for manipulation.
In conclusion, Gravestein's article offers a thought-provoking exploration of the evolving relationship between technology and spirituality. He argues that as AI becomes increasingly sophisticated, it's essential to consider its potential impact not just on our practical lives but also on our fundamental beliefs and values, as it might just be on its way to becoming the religion of the future.
The overfitted brain hypothesis - ScienceDirect
This article explores Erik Hoel's novel hypothesis on the purpose of dreaming, which draws intriguing parallels to machine learning concepts.
Key Points:
Dreaming and Learning: While the exact function of dreaming remains elusive, research suggests a strong link between dreaming and learning.
Quote: "The reasons for how and why we dream are poorly understood; however, the suppression of sleep stages most closely associated with dreaming have been known to impair learning in mammals for some time."
Explanation: Disrupting dream-rich sleep negatively impacts learning, implying a crucial yet undefined role of dreaming in the learning process.
Traditional Machine Learning Models of Dreaming: Previous attempts to explain dreaming through machine learning focused on aligning "recognition" and "generative" models in the brain.
Quote: "According to this theory, dreams are a way of aligning our recognition pathways with our generative pathways, and so, over time, dreams should come more and more to resemble that which is experienced during waking."
Explanation: This perspective, inspired by algorithms like the wake-sleep algorithm, suggests dreams help the brain fine-tune its internal models to reflect waking experiences better, leading to increasingly realistic dreams over time.
Hoel's Overfitting Hypothesis: Hoel proposes a different view: dreams serve to prevent "overfitting" in the brain's learning process.
Quote: "Specifically, Hoel’s hypothesis is that dreams help to prevent overfitting. Specifically, he proposes that the purpose of dreaming is to aid generalization and robustness of learned neural representations obtained through interactive waking experience."
Explanation: Just as overfitting in machine learning leads to poor generalization, Hoel suggests that dreams, by introducing variations on waking experiences, help our brains develop more flexible and robust representations of the world.
Dreams as Regularization: Dreams act like a form of "regularization," a technique used in machine learning to prevent overfitting and improve model generalization.
Quote: "This proposal is different from EM-style proposals because the dream phase is not used to improve the match between a generative model and a recognition model, but rather to regularize a single model."
Explanation: Unlike previous theories, Hoel's hypothesis doesn't aim to make dreams mirror reality. Instead, dreams introduce controlled "noise" or variations, similar to data augmentation techniques in machine learning, leading to more adaptable and less rigid internal models.
Implications for AI and Neuroscience: Hoel's hypothesis offers exciting avenues for both fields.
Neuroscience: It provides a compelling explanation for dreams' bizarre and unrealistic nature, which previous theories struggled to capture fully.
AI: It inspires new algorithm designs that incorporate dream-like processes to improve generalization in artificial neural networks, potentially leading to more robust and adaptable AI systems.
Dream Substitutes and Future Research: Hoel's theory opens the door for exploring "dream substitutes" - artificial stimuli designed to mimic the beneficial effects of dreaming.
Quote: "Finally, Hoel speculates on the use of dream substitutions—dream-like stimuli generated to aid learning during wakefulness or to ameliorate the effects of sleep deprivation."
Explanation: This concept could lead to novel interventions for learning enhancement or mitigating the negative effects of sleep deprivation, potentially leveraging technologies like augmented reality. Additionally, the authors speculate that psychedelics, by altering neural variability, might function as naturally occurring dream substitutes.
Why it Matters: Hoel's overfitting hypothesis provides a novel and compelling explanation for dreaming, with potential implications for understanding the human brain and advancing artificial intelligence. This theory bridges the gap between neuroscience and machine learning, offering a fresh perspective on how our brains learn and adapt to the world's complexities.

The Turing Test and our shifting conceptions of intelligence | Science
The article discusses the Turing Test, proposed by Alan Turing in his 1950 paper "Computing Machinery and Intelligence." Turing introduced the test as a thought experiment to explore whether machines could exhibit intelligent behavior indistinguishable from that of humans. The article explores the historical significance and modern interpretations of the Turing Test and recent claims that modern chatbots like OpenAI's ChatGPT and Anthropic's Claude have passed the test. It also delves into the philosophical and practical challenges of using the Turing Test to gauge machine intelligence.
Key Points
1. The Turing Test as a Thought Experiment
Key Point: Turing proposed the Turing Test to combat the intuition that machines cannot think due to their mechanical nature.
Explanation: Turing's test involves a human judge conversing with a computer and a human (a "foil"), each trying to convince the judge that they are human. Based on the conversation, the judge then guesses which is the real human.
Key Quote: "Turing imagined an ‘imitation game,’ in which a human judge converses with both a computer and a human (a ‘foil’), each of which vies to convince the judge that they are the human."
Why It Matters: This thought experiment challenges the notion that thinking is exclusive to humans and opens the door to considering machines as thinking entities.
2. Passing the Turing Test
Key Point: The Turing Test has become iconic in the public's mind as the ultimate milestone of artificial intelligence (AI).
Explanation: Recent claims suggest that modern chatbots like ChatGPT and Claude have passed the Turing Test, indicating they can perform human-like conversation.
Key Quote: "Now, nearly 75 years later, the reporting on AI is full of pronouncements that the Turing Test has finally been passed by chatbots such as OpenAI’s ChatGPT and Anthropic’s Claude."
Why It Matters: Passing the Turing Test is a significant achievement in AI, suggesting that machines can exhibit human-like intelligence.
3. Criteria for Passing the Turing Test
Key Point: There is little agreement in the AI community on the criteria for passing the Turing Test.
Explanation: Turing's description of the imitation game was short on details, and various interpretations have emerged. Some have taken Turing's prediction that a computer could fool an average interrogator 30% of the time in a five-minute conversation as the official criterion.
Key Quote: "Because he was not proposing a practical test, Turing’s description of the imitation game was short on details. How long should the test last? What types of questions are allowed? What qualifications do humans need to act as the judge or the foil? Turing didn’t specify such fine points."
Why It Matters: The lack of clear criteria makes it challenging to determine whether modern chatbots have passed the Turing Test.
4. Controversies and the ELIZA Effect
Key Point: The 2014 Turing Test competition, won by a chatbot named Eugene Goostman, was met with skepticism from AI experts.
Explanation: The competition's results were criticized for being a test of human gullibility rather than machine intelligence. The ELIZA effect, named after the 1960s chatbot ELIZA, highlights our tendency to ascribe intelligence to entities that can converse with us.
Key Quote: "AI experts, reading the transcript of Eugene Goostman’s conversations, scoffed at the claim that this unsophisticated and unhumanlike chatbot had passed the kind of test Turing had in mind."
Why It Matters: The controversy underscores the importance of rigorous testing and expert evaluation in determining machine intelligence.
5. Evolving Definitions of the Turing Test
Key Point: The Turing Test's meaning has evolved over the years. It is often used to describe any interaction in which a computer seems human-like.
Explanation: Recent claims about chatbots passing the Turing Test often refer to different versions, some of which do not align with Turing's original concept.
Key Quote: "The meaning of the term ‘Turing Test’ in public discourse has evolved over the years into something considerably weaker: any interaction between a human and a computer in which the computer seems sufficiently humanlike."
Why It Matters: The evolving definition highlights the need for clear and consistent criteria in evaluating machine intelligence.
Conclusion
The article concludes that the Turing Test, while iconic, is not a definitive measure of machine intelligence. The lack of clear criteria and the evolving definition of the test make it challenging to determine whether modern chatbots have truly passed the Turing Test. The test's focus on fooling humans rather than directly testing intelligence has led many AI researchers to dismiss it as a distraction. However, the test's prominence in popular culture persists, reflecting our intuitive assumptions about intelligence and human-like behavior.
Key Takeaways
The Turing Test as a Thought Experiment: Challenges the notion that thinking is exclusive to humans.
Passing the Turing Test: Recent claims suggest modern chatbots have passed the test, indicating human-like intelligence.
Criteria for Passing the Turing Test: Lack of clear criteria makes it challenging to determine whether modern chatbots have truly passed the test.
